I Totally agree with you Victoria but the Problem is that the doctors are now saying to me that because of the little wheel that talks about the weeks i didnt conceive until i was two weeks from what the wheel says that makes no sense I thought that i had conceived on june 25 and that like you said 40 weeks after im due april 1 so how is it he says i conceived july 10? im going to have to change my doctor he doesnt kno what hes talking about.
my dr told me my daughter was due 6/21 by my last pd. also even when he did the sonogram it was that date. i had her 6/1. the babies typically grow at the same rate while they are young and then as the fetus gets older they rates of growth very. if you had a sonogram, they are TYPICALLY correct.
Sometimes they are not correct in their calculations. Sounds like you may have conceived 2 weeks after your period started, but everyone ovulates differently, thats just a possibility. If you were tired and dizzy way sooner than they are saying you conceived, you are probably the correct one. They may change your due date later depending on the measurements of the baby. April 1st doesn't seem right at all!
I did a quick check on this web site (http://www.americanpregnancy.org/duringpregnancy/pregcalc...)
If your due date is April 1st, then it estimates that if you have a 28 day cycle, then the first day of your last period was June 24, and you probably conceived July 9th, and you're now 16 weeks along.
My 4 yo daughter was due March 25th (just a week before you're due date) and I conceived her around the 4th of July, so with your due date April 1st, then July 9ish is correct.
If the baby is due in April you would have conceived in July.....From July to April is nine months
I've never understood that either, I asked the doc to explain but his answers were confusing. All in all, if they measured the baby, it's correct. If they make a mistake then it is usually only a few days off.
Generally speaking women have a 28 day cycle in which you ovulate (generally) about 12-14 days after the first day of your period. And a "window" of about 2 -3 days to become pregnant around the time of ovulation. If you have a "normal" cycle of 28 days (not everyone does!) you would typically ovulate (have the 2-3 day window where you can become pregnant) around the 14th day of your cycle. But since some women's cycles are often longer (or shorter) than 28 days, the "window" can be closer to the 16th or 19th days or so. Basically, it will be about halfway through your cycle. If your cycle is normally 32 days, then your window would probably be around day #16 (not day 14). If your cycle is 38 days, your window would be around day #19.
When I was trying to conceive with our second child, my cycle varied widely from 24 days to as many as almost 50 days!
Once you understand that, then you just use that date and count forward 40 weeks. A pregnancy is NOT 9 months. It is actually a bit closer to 10 months.
So if your last period began on May 29, and you have a "normal" cycle of about 28 days, you would count 14 days into that cycle (which would be June 12) and then from that date count 40 weeks. That would estimate your due date to be March 19. If you have a longer cycle then you might need to move the conception date back a few days more. And keep in mind, that illness, stress or other factors can influence when you actually ovulate. So if you adjust the date a week or two for stress or a longer menstrual cycle, then you could easily have an April 1 due date.
It seems highly improbable that you started your period on May 29 and did not become pregnant until July 10. That would mean that you didn't ovulate until around day 42 of your cycle! It seems EXTREMELY more likely that you conceived closer to day 27 of your cycle.
And the April 1 due date you were given by your doctor EXACTLY corresponds with 40 weeks from June 25.
If you still have concerns then you should discuss them with your doctor. He/she must maintain patient confidentiality and not disclose your concerns with others. It is important for you and your baby's health to not be so stressed out over this, and information is what you need to allay your fears. Have your doctor to explain to you exactly how your due date (which is just the reverse of saying date of conception) was determined. Was it strictly by the possible dates of conception you gave him? From the date of your last period? From measuring your uterus? Or some combination of all three? If the baby measures differently than what they would expect judging from the date of conception, then that should be brought to your attention, and I'm sure will be as it can relate to health issues of the baby.
But please talk to your doctor and get them to explain in detail how they arrived at your date of conception. It is important (not just for the reasons you are after at the moment) but for your and your babies HEALTH.

Plug in the first day of your last period and it will give you all the dates.

If your last period was 5/29/09 as you say, then you should be due 3/4/10 with an estimated conception date of 6/12/09.
If your due date is 4/1/10, then your last period would have been 6/25/09 with an estimated conception of 7/9/09???
Something's not adding up dear!?!?!?!?!
Unless they did an ultrasound and that said your due date was April 1, based on your last menstral cycle it should be march 5. The only way it could not be that date is if you've had an ultrasound and they measured the baby.
Hi D.
Your best bet is to go to your doctors get a sono-gram and ask if they have a birth wheel to explain how they determine your due date. If you don't have insurance,go to the health department and tell them you don't have insurance and they will refer you were you should go. Good luck
