Pregnancy due date by conception

Common Questions and Answers about Pregnancy due date by conception

pregnant

Avatar f tn i quite agree with you. freaks a lot of fathers out. but, from the first day of your last period it is. maybe because conception has quite a timeframe where it can occur after sex...i don't know. i'd prefer if they used a likely conception time as the start of pregnancy though.
Avatar f tn I say the first guy is the dad bc you are fertal for 7 days and then you ovulate on the 7th day and then from there it takes a few days for implantation to take place which would put you around your estimated conception date. Plus if your estimated conception date was feb 2 and you didn't have sex with the other guy until the 7th-10th there's no way he is the dad!
Avatar f tn The first day of my last period was June 7. I had sex on the 18th and 20th and was ovulating around the 21st. I am now pregnant but am wondering if I am 3 Weeks pregnant or 5 Weeks. Due date predictors and various websites say I am five Weeks because the gestational age starts the day of your last menstrual period. This gives me a due date of March 14th which is only 38 Weeks after conception. Shouldn't I be 3 Weeks along with a due date two Weeks later at 40 Weeks after conception?
Avatar f tn Doctors calculate pregnancy using a 40-week calendar, though from the date of conception, pregnancy is only 38 weeks long. They go back and start the count on the first day of your last period. This is the way doctors have dated pregnancy for a long time, certainly from before the invention of ultrasounds, because the first day of a period is a noticeable signal and known date, and ovulation is hidden and happens on a date not usually known.
Avatar f tn Now if I count backwards from my due date to my date of conception, it's 40 weeks. And I am positive about both my LMP and my date of conception. Does this mean that my midwife counts differently or is my due date incorrect?
Avatar f tn So you usually go 40 weeks from conception to get your due date.. so I think its jan. 20th. But that's just what I think!
Avatar f tn ), and January 5 is the only time you had sex, then that would be considered your conception date. Your due date would be 38 weeks from then. Based on a due date calculator, your due date would be September 28, 2010. Good luck to you.
Avatar f tn If you know the exact conception date than go by that. Mine was confirmed by an ultrasound , but I tracked my period as well so.
Avatar m tn If her first ultrasound was at 5 weeks, it will be the most reliable for working out a conception date.
Avatar n tn Here's what the conception calculator says regarding the due date of November 28. How early in the pregnancy was the ultrasound that gave you the due date? If you really slept with the other guy only at the end of January, he is probably out of range even if you had a later ultrasound. Do you have any way to confirm that it was no later than the end of January that you slept with him?
Avatar f tn A dr usually wont change a due date over a week difference in growth or even two weeks but they have to go by baby since sperm doea live in you for several days up to a whole week even.
Avatar m tn No. You didn't get pregnant in October.
5111430 tn?1377663221 date of ultrasound GA at that date (i.e., weeks/days) est. due date Also, of course, remember that a GA count begins on the first day of your last period, with an estimated conception date being about two weeks later.
Avatar f tn I have a due date of Jan 4th, the whole cenception conceiving 2 weeks gap all that CONFUSES me! can anyone just say straight out if it could be from the day i had SEX April20-24? or do u think its from rlier then that?
Avatar f tn It was new to me, I have 2 kids already. But I have had one due date off by a whole month with my oldest son. The due date they gave him was Nov. 16th and he was born Oct 16th.
Avatar f tn Okay so I am pregnant with my 4th child and I have never understood how they calculate how far along you are. It is not possible to be pregnant on the first day of your period so to count day 1 as pregnancy day 1 seems stupid to me. Now my due date and the Dr.'s due date are only different by a day so it shouldn't matter much except that by putting me 2 weeks ahead of my pregnancy by going from my period would put baby 2 weeks ahead in testing and ultrasound.
5891248 tn?1406410864 My doctors say I am due March 6th but I know the one time my husband and I had unprotected sex wastwo days before the conception date they have. They prefer going by their ultrasounds than us lol.
Avatar f tn So once it calculates that it gives me a whole different due date and date I conceived. Now I tried by putting my due date and it tells me a different day I conceived and my correct weeks of pregnancy. So idk if to go based off the due date. Has anyone had this problem? Thank you.
Avatar f tn Idk if you did an ultrasound yet or was giving a due date but from my calculations you should be due around August 6. If it was the 2nd dude your due date would be around August 20th. I hope this information was helpful..good luck!
Avatar n tn Did your dr base your first due date off of an early ultrasound (6-8 weeks)? If he did, you base your conception date off of that. Your due date may have changed now just because your baby seems to be growing at a different rate. Early u/s are very accurate and are usually only off by a few days if any.
Avatar m tn Did you get the February 13 due date early in the pregnancy from a doctor reading your ultrasound results?
Avatar m tn It does sound like you were already pregnant by the 11th. Your conception window based on your due date is November 29 to December 7. If you were to try to compute from your period instead of from the ultrasound (which is never a good idea), it would put the window even further back.
Avatar n tn They can tell by giving you a blood test it will give most accurate due date by your hormone levels
408496 tn?1269603350 Which one do doctors usually go by? I used the due date calculators to figure these and they are 2 weeks apart. Just wondering if anyone had any input...
