Hi, I need some answers if
 
Hi,

I need some answers if possible, it might sound a bit complicating but i will try and make sense ha ha. I was with my ex boyfriend for a year and a half, we split up BUT i slept with him on the 6th Nov, and i came on my period on the saturday/sunday morning. On the following week 14th Nov i slept with this lad ( my bf now ) and then on the 11th Dec i found out i was pregnant,.But when i went for my 12 week scan they told me i was 12 weeks 5 days, which means i got pregnant on the 13th Nov. I am so confused please help

Re: When Did I Conceive? How to Calculate Your Conception Date
 
EmmaOxx, has anyone helped you with your question?

First of all, congratulations. :) The gift of life is a blessing from God.

It sounds to me that the medical professionals are relying on their typical calendar wheel -- which isn't actually very accurate. The first half of your cycle, from period to ovulation, is called the follicular phase. The second half, from ovulation to period again, is the luteal phase. While the luteal phase is almost always around 13-15 days, the follicular phase varies in length from woman to woman, even sometimes by as much as weeks, according to when ovulation takes place in the body.

I would need more information from you (period dates) to get a better idea, but it sounds to me that you ovulated later than the medically prescribed day 14 of the follicular phase (which most women do). This could be why the doctor says you conceived on the 13th, which by your calculation is one day too early to be possible! Also bear in mind that, during your fertile phase in the days leading up to ovulation, your body creates cervical fluid that can keep sperm still living for up to 5 days in order to give sperm the best chance of reaching their goal in the hour or so that the egg is finally in place. Once ovulation has occurred, it is no longer possible to get pregnant until the next cycle.

So... IF the doctor is assuming that 13th November was the day you ovulated, but in fact you did not ovulate until a more typical few days after that, it is highly possible that 1) you were in your fertile phase on 14th November, 2) your body kept the sperm alive, and 3) you ovulated and conceived in the day or several days later.

The medical professional practice of calculating all ovulation at day 14 of the follicular phase is incredibly unhelpful, inaccurate, and results in many more "emergency" c-sections and induced labor than is necessary. Every woman's body is different. Every cycle may be different, too, and it is a rarely blessed woman who can rely on a closely consistent cycle length from one month to the next! Most of us vary at least a day or two, the unluckier varying sometimes even by weeks. This means that a woman who ovulated later would be told that she were due on such-and-such a date, when in actuality she might not be due for another 3 to 10 days after that date!! Do you see how she and her baby could both be in perfect health and time, but the doctors would be pressing an induction on her on the basis that she is 10 days "late"?

I suggest that you do some research on your rights as a mother and a woman. Decide what care is best for you and your baby, and don't be bullied into a procedure that might not be the right thing for you -- whether that is in hospital or at home, with an OBGYN or with a midwife, with an induction or naturally, in water or in the stirrups, with medication or with massage or nothing. You have the rights to say what happens to your body. How comfortable and informed you are with the steps of labor, or how uncomfortable and invaded and confused you feel, can have a great impact on your post-natal physical recovery as well as emotional, the success of natural birth or whether your stress requires unplanned medical intervention, and how you bond with your child. Make an informed decision.

I am now 23 weeks pregnant and been surfing the web a lot lately trying to find out when I conceived I'm due on March 12, 2012 and very concerned about who might be the father of my child. Me and my boyfriend of 2 years broke up in June we had intercourse a lot never pulled out then on June 9th I had sex with a another guy we did use protection and after that that same weekend my and my current boyfriend got back together and been together since.

Okay so i had a bf last year
 
Okay so i had a bf last year on november and we were on and off. We broke up this year 2011 on july 10. We last had unprotected sex on the last week of june but he took it out before he came inside me. After we broke up, a couple of days later i had sex with other guy. We use two condoms but they broke. He said that he didnt came. After i had sex with that guy on that same month i got my period. It was like around july 27, but my period wasnt normal. It only lasted 3 days and it was super light. Now im pergnant and im 24weeks today. My due date is on april 8, 2012. I need your help ! I dont know who the father could be.

Re: When Did I Conceive? How to Calculate Your Conception Date
 
SMH - I can't stand when people stated that you are pregnant for 40 weeks which equals 10 months. Pathetic. Let's do a simple math problem shall we?

1 year = 365 days
365 days/12months= 30.4166days

so there are on average 30.4166 days in each month.

30.4166 days in a month / 7 days in a week = 4.3452 weeks in a month

(Look at a calendar... how many months can YOU find that are exactly 4 weeks (28 days).. 11 out of 12 are more aren't they?)

So 280 days DOES equal 40 weeks. (280/7days=40weeks)

But is 40 weeks REALLY 10 months as this site and a few other misleading sites claim?

Let's see:

280/30.4166 (b/c we saw earlier that this is the average of how many days there are in each month) =9.2 months

And the .2 just about another week. .2*30.4166=6days. So you are pregnant for about 9 months and one week. (or atleast SCHEDULED DUE DATE for that length of time, the baby decides on his own when he is ready, lol)


Think about it.
For example, MY LMP is June 22.
9 months later is March 22.
10 months later is April 22.
Guess when my due date is? MARCH 28!
That's 9 months and 6 days AFTER my LMP.. 40 Weeks after my LMP.

I wish people would get this right. Your due date is about 9.2 months after LMP NOT 10. Stop assuming months are 4 weeks. Because that is rounding TOO severely and it REALLY throws it off. smh. The math is not that hard.

(These numbers are rounded off so it is still not EXACT - but it sure is a whole lot closer than misleading people and saying 10 months! smh. Pull out a calculator and fiddle with the numbers yourself.)
