Ok, numbers are not my strong point but this is confusing.
1. According to most calcuators from first day of last period, Aug. 2 S is due on May 8.
2. NP told S we would be due May 10.
3. Our journal counts Lunar months and says we are due May 7.
So, S tells me we are starting our 7th week today. The ticker (set for May 10 due date) says we are about to start our 5 weeks 5 days. Our journal says we are starting our 5th lunar week (second month) today. Would some one just help me focus. I think I'm following S's logic (she is the smart one) and I'm changing the ticker to due date of May 7. *****S I hope you don't mind****
So confused....am I the only one that doesn't get this?

OMG, that stuff drove us CRAZY!! I think in the end we just had to pick one method at random (or justify randomly which one was "right") and just not look back - otherwise you will go insane and in the end should be awarded an advanced calculus degree. :-)
since we had extra long cycles, the numbers would have been a little off if we had calculated from the first date of the last period. we always calculated from the date of conception (which was either the date of the insem or the day after). we were told that the date of conception would officially be the start of the third week of the egg's growth/pregnancy, and that at 14 days post ovulation, when most people get their first positive test, you're actually finishing up the fourth week of growth of the egg and the end of the second week post conception. confusing, indeed.
Geee. Thanks *G*. You confused even more. :) You were always better at stats and stuff than I was in school too.
haha...okay, here's another way we looked at it. our insem was on a wednesday. so, we'd say, how many wednesdays has it been since the insem? say it had been 22 days since the insem - that's three wednesdays plus one day, or three weeks plus one day. add two weeks to account for the pre-ovulation part of the cycle, and that makes you 5 weeks and 1 day pregnant. at least that's how it was explained to us :)
That is so confusing! It is amazing that there are so many ways to calculate the due date! I guess though, the baby doesn't really care about the calculations and will come when it is ready!
Have you tried one of those due date calculators? I know a lot of people swear by them. There's one for Assisted Conception cycles at http://ivf.ca/calcu.htm
It is all very confusing. I also have *G*'s problem of never ovulating anytime near CD14, so I've managed to confuse a few nurses by explaining my that "actual" due date was almost 2 weeks later than what they had calculated.
Due dates are only an estimate in the end, anyway, so feel free to take the average!
No matter what date you come up with, just know that your OB/midwife/etc. will come up with another one entirely. We belabored the point for awhile, but realized by the 'big' ultrasound that we needed to just set everything to match the doc's chart. Was she born on that due date? No. Was she born on 'our' due date? No. She was born on her birthday. Kids!
hahaha I am totally lost by that as well. They are close dates, so I would just go in the middle. I think even with the u/s they are off by a couple days. I was 9 days past my due date so I think it's all an educated guess : )
Hurray!!!!!
I say pick the later date, that way when the baby is still in the oven on May 7th you won't think you are late. Lilly didn't want to be born, she was 2 weeks past her "due date" and it almost made me go crazy, and you know I was close anyway :) ahahha "social workers" :)

Could you just choose April 27 as the due date...you know, because it's a good day and all...? ;-)
I wheeled you out at May 7th, also. It really doesn't matter the difference of a couple days since your due date is "give or take" 2 weeks, which is why we say term is 38-42wks. You might as well go with the NP, because that is what will be on your prenatal record, so everytime you go in, or if you are ever in triage they will go by that date. When you have your first ultrasound you will probably get yet another date a couple days off from these, but your LMP is usually the date used, especially in the case where you know the exact date of conception. That is one of the fortunate things of having all the timed/planning we do to conceive. :-)
Congratulations!
The pregnancy math is maddening. I just went with the "Pregnancy Journal" since the first day I wrote in there was the day I went for my insemination. I delivered pretty close to the due date at the end of that book.
