The answer is YES! Can women have fraternal (non-identical) twins? Of course! This happens when two eggs are released and two different sperm fertilize them. If a woman had sexual intercourse with two men within the window of opportunity, then it is possible for each of those eggs to be fertilized by different fathers.
Does this need to be in the same day? The answer to that question is NO! Sperm can survive for 5 days in a woman’s body. The eggs can live up to 48 hours. This means that you could have intercourse 5 days ago, have intercourse again with a different person days later. You ovulate with two eggs and become pregnant with both eggs. What are the odds? Does it matter? It only takes one sperm out of thousands to make it through.
I am sure this happens more times than is reported. I can’t imagine too many women coming forward that they cheated on their spouse, after the birth of their children. That is most likely a secret that no one will ever know.

Pregnancy tests pick up the presence of hCG in the urine. Human chorionic gonadotropin (hCG) is the hormone produced by the placenta. It starts to be produced as soon as the fertilized egg implants into the lining of the uterus. Since this happens 6 to 12 days after conception, any time you test too early, you will see a negative result because there is not enough hCG in your system yet.
The most sensitive pregnancy tests can detect 20 mIU of hCG. This level may be detected as early as 6 to 8 days past ovulation, but most women will still get a negative result this early. On average, most implantations occur between 8 to 10 days after ovulation, so you may be testing and your baby hasn’t even implanted yet. The closer you are to when you expect your period, the better luck you’ll have getting an accurate result.
Even if you get a negative result, if you still miss your period, retest. By the day after a missed period, 90% of women will get a positive result. The remaining 10% will still test negative even though they are pregnant. In that case, you may want to go to your care provider and get a blood test done. Blood tests can pick up extremely small amounts of hCG, but even they cannot confirm a pregnancy until at least a week after ovulation.

Pregnancy can give you more questions than answers, especially if this is your first time experiencing it. Luckily, there are many places like this one that can help answer those questions and calm your fears. Pregnancy is a natural function of your body. It knows how to grow a baby; you need only let it do its job.
Over the next couple of weeks we will address the top questions that most women have when they become pregnant.
1. Am I pregnant?
This is one of the most important questions a woman faces when she thinks she may be pregnant. There are many home pregnancy tests available. Home pregnancy tests are likely to be the most accurate on the day you expect your period to arrive, which may be 12 to 16 days after you ovulated. If you wait until the following week and your period still hasn’t arrived, test again. If you are still getting a negative result, contact your doctor for a serum blood test. For a very few select women, the home pregnancy tests just don’t seem to measure the hcG.

What part of the cycle decides how long it your whole cycle will be? I know all cycles are different for different women but where does the variance occur? Is it the days from your last period to ovulation or the days from ovulation to your next period? If I use an ovulation predictor kit and it says I ovulate today will conception happen in one week and implantation one week from conception and my missed period be one week from implantation? Or can ovulation, conception and implantation be further apart than one week? Let me know if I’m not being clear enough in my question.
Typically you ovulate midway through your cycle. During a 28 day cycle you should ovulate on day 14. This can vary and be a little early or later. The key concept according to my OB/GYN is that the luteal phase is 14 days long (see below for further information). He recommends having sex between CD8 and 18 every other day if you are trying to get pregnant (CD= cycle day, counting CD1 as the first day you start your period). Here is some better information that I hope answers your questions: A woman’s monthly cycle is measured from the first day of her menstrual period until the first day of her next period. On average, a woman’s cycle normally is between 28-32 days, but some women may have much shorter cycles or much longer ones. Ovulation can be calculated by starting with the day the last menstrual period (LMP) starts or by calculating 12-16 days from the next expected period. Most women ovulate anywhere between Day 11 – Day 21 of their cycle, counting from the first day of the LMP. This is what many refer to as the “fertile time” of a woman’s cycle, because sexual intercourse during this time increases the chance of pregnancy. Ovulation can occur at various times during a cycle, and may occur on a different day each month. The Ovulation Cycle Divided into Two Parts: The first part of the ovulation cycle is called the follicular phase. This phase starts the first day of the last menstrual period (LMP) and continues until ovulation. This first half of the cycle can differ greatly for each woman lasting anywhere from 7 days until 40 days. The second half of the cycle is called the luteal phase and is from the day of ovulation until the next period begins. The luteal phase has a more precise timeline and usually is only 12-16 days from the day of ovulation. This ultimately means that the day of ovulation will determine how long your cycle is. This also means that outside factors like stress, illness, and disruption of normal routine can throw off your ovulation which then results in changing the time your period will come. So the old thought that stress can affect your period is only partly true. Stress can affect your ovulation which ultimately determines when your period will come, but stress around the time of an expected period will not make it late—it was already determined when it would come 12-16 days earlier! From the Menstrual Period to Ovulation (the details you may not know!) When your menstrual cycle begins, your estrogen levels are low. Your hypothalamus (which is in charge of maintaining your hormone levels) sends out a message to your pituitary gland which then sends out the follicle stimulating hormone (FSH). This FSH triggers a few of your follicles to develop into mature eggs. One of these will develop into the dominant follicle, which will release a mature egg and the others will disintegrate. As the follicles mature they send out another hormone, estrogen. The high levels of estrogen will tell the hypothalamus and pituitary gland that there is a mature egg. A luteinizing hormone (LH) is then released, referred to as your LH surge. The LH surge causes the egg to burst through the ovary wall within 24-36 hours and begin its journey down the fallopian tube for fertilization. The follicle from which the egg was released is called the corpus luteum, and it will release progesterone that helps thicken and prepare the uterine lining for implantation. The corpus luteum will produce progesterone for about 12-16 days (the luteal phase of your cycle.) If an egg is fertilized, the corpus luteum will continue to produce progesterone for a developing pregnancy until the placenta takes over. You can begin looking for pregnancy symptoms as early as a week after fertilization. If fertilization does not occur the egg dissolves after 24 hours. At this time your hormone levels will decrease and your uterine lining will begin to shed about 12-16 days from ovulation. This is menstruation (menstrual period) and brings us back to day 1 of your cycle. The journey then begins all over again.

I would like to know what kind of pregnacy symptoms do you get starting FROM CONCEPTION to before your period is due, if any? I have looked at other answers but they are talking about 2 weeks after the period is due, but I already know that if you miss your period that is the biggest sign. Please answer if you know of any, because I am on clomid and this my third month and last try for getting pregnant with clomid and so far it seems like it has not worked. I am so anxious to know before my period is due as to what the symptoms are. Thanks for your kind answers.
The reason there aren’t any signs is because you have to wait for baby to implant for it to start affecting us if its going to. Some get spotting 7-10 days after ovulation. Others wait for there period because testing to early could give them a false negative. Normally 2 weeks after ovulation is about the time you would get your period, about the time you HCG levels are high enough to show up on a HPT. Some ppl think symptoms in there head, but in all reality, there false. Some do become pregnant and others don’t. First signs are sore breasts, cramping, bloated. All happen about 10+days after ovulation everyone is different and drugs make your body do weird things. Good luck!

The two methods of calculating your pregnancy are the American System and the Ovulation System. Today we are going to discuss the Ovulation Calendar. It seems that this system is used more frequently with more accuracy. The fact of the accuracy and of course the method is so easy to do it is no wonder that many people prefer the Ovulation Calendar.
The Ovulation Calendar is of course up to you to keep track in order to get a more perfect result. I am going to give you an example that I am sure will be very useful for you.
MONTH 1:
o 10/01/06 First day of your cycle
o 10/12/06 A little bit fertile
o 10/13/06 Fertile
o 10/14/06 VERY fertile
o 10/15/06 Time to ovulate
A home pregnancy test may work now.
o 10/29/06 End of cycle
o 11/01/06 No period? Maybe you’re pregnant?
o 7/08/07 If you are, this is your approximate due date.
This is a very good example to use when you start your Ovulation Calendar. You may not be pregnant about 15 to 25 per cent of most women have a chance to get pregnant during their first cycle. About 50% of couples conceive during the first three months. The first six months about 75% of couples conceive. The first year about 90% of couples conceive giving birth to their beautiful baby.
The Ovulation Calendar is very important to couples and that is why I am going to present a version of the second month for your benefit. The average couple who has sex once per day provides the best chance of getting pregnant. When your partner ejaculates remain on your back with your hips elevated for 20-30 minutes this will optimize your chances of getting pregnant. Another good suggestion for you and your partner to remember is that the woman on top position is not great for pregnancy since ejaculate may flow out.
*MONTH 2:
o 10/29/06 First day of your cycle
o 11/9/06 A little bit fertile
o 11/10/ Fertile
o 11/11/06 Very Fertile
o 11/12/06 Time to ovulate
o 11/26/06 End of Cycle
o 11/29/06 No period? Maybe you’re pregnant!
o 08/05/07 If you are, this is your approximate due date.
You deserve to know how soon you have become pregnant. There are several tests on the market that can do just that. The EPT early pregnancy test is better than others on the market. EPT is a home pregnancy test that can tell you a lot sooner than ordinary pregnancy tests on the market today. When using the Ovulation Calendar let us suggest that you keep on hand the EPT early pregnancy test so you can test yourself at the proper times. We had suggested that about 50% of couples conceive within the first three months. In order to help you maintain your Ovulation Calendar we will continue with the third month for your benefit.
*Month 3:
o 11/26/06 First day of your cycle
o 12/07/06 A little bit fertile
o 12/08/06 Fertile
o 12/09/06 VERY fertile
o 12/10/06 Time to ovulate
o 12/24/06 End of cycle
o 12/27/06 No period? Maybe you’re pregnant!
o 09/02/07 If you are, this is your approximate due date.
When calculating your pregnancy and you discovered that you are now pregnant. The Ovulation System has its own way of calculating the due date. Conception is considered week 0, week 2 is positive pregnancy test should be taken, weeks 10-11 ends the first trimester, while week 24 ends the second trimester leaving week 38 your due date. The Ovulation Calendar is very important in calculating when you ovulate to know when you have conceived. The Ovulation Calendar is also good to keep after you know you’re pregnant in order to chart your due date. One of the most
An important thing in life is creation of new life. That is why a woman should be able to calculate when her baby will be born, when she should be ready to go to hospital for delivery, and most of all know what is going on inside her.
