Conception date: Generally women ovulate about a week after the last day of their period. However, if your periods were not regular prior to conception, then your ovulation timing may be different. Based on your due date and first day of your last menstrual period, you likely ovulated around March 27th, and conceived between March 23rd-31st. Again, this is based on a 28 day cycle. ...Read more
Yes,but: You don't want baby to come that early.If you think you are having signs of early labor you need to contact your OB and discuss it.

I had my 1st u/s done on 6/25/12 & i was 9 weeks & 6 days given a due date of 1/22/13, not sure of my lmp. After 6wks the fetus double in size?
May 1st conception: Usually when people ask this question, they're interested in when conception happened. Based on the ultrasound due date, the conception was somewhere between april 24th and may 8th. The LMP may vary from woman to woman but with a normal 28 day cycle, it would have been april 17th. ...Read more
Lmp was 4/27. After first u/s on 6/23 i was given a due date of 2/17. On 8/12 i was given 2/5 as my dd. when was conception? Can this be late ovulatio
First ultrasound: It seems that your first ultrasound is likely your best one, thus the due date of 2/17 would be the most accurate. 2 months later, the ultrasound is going to be less accurate, so unless your doctor actually changed your due date to 2/5, your 2/17 EDD is likely still the best one. Based on that, likely "approximate" conception date was around 5/27/14. ...Read more
5wk 4 day ultrasound vaginally, given the due date january 15th. Is that due date accurate? Given conceiving date 4-19/ 4-25.

I am 33 weeks 4 days pregnant, the dr has given me a due date of april 17, 2013 based on ultrasound. When is the most probable day/days of conception?
Subtract 2 weeks: When "calculating" this, we assume a 28 day cycle with ovulation on day 14. So obviously, it is just an estimate. To get approximate conception date, subtract 2 weeks from your current gestational age. That will then be how many weeks ago you conceived. So in your case, your date of conception is approximately 31 weeks 4 days ago. ...Read more

An Estimate: A due date is only an estimation. Labor is brought on by a complex interaction of hormones and other factors between the baby and the mother that are impossible to predict at this point. Labor doesn't care about the calendar but most deliveries will occur by 42 weeks. Your Ob may recommend inducing labor artificially if things drag on too long. Best wishes! ...Read more

Dont know lmp... First ultrasound was given to me 10/22/13 it read 8w5days and due date was 06/02/14 now due date is 05/30/14 which is correct?
Similar: First, only 5% of women deliver on their given due date. Secondly, those 2 dates are so close, it's impossible to say that one is more accurate than another. I usually say that the earlier ultrasounds are more accurate than the later ones. But it depends upon the sonographer and the resolution of the machine. Generally first trimester scans are +/- 7 days. And 2nd tri scans are +/- 14 days. ...Read more

Was given an early dating ultrasound due to paternity that showed due date of Oct 10. Is there any chance I could've conceived dec 23?
Impossible: You did not get pregnant before your last menstrual period. You got pregnant in January. Remember a pregnancy lasts forty weeks from the last menstrual period. Your questionable date is way beyond that natural limit. You conceived this child 1/17/2014 from sex sometime on 1/12/2014 to 1/17'2014.

I was given two due dates, Oct. 31 & Nov. 4, depending on those dates is there any way I could have gotten pregnant Febuary 17 or anytime after?
What are those dates: based on? Last period? Ultrasound (if so, what trimester?) The dates you have given suggest that Feb 10 is the latest you could've gotten pregnant, and likely earlier - but without knowing the accuracy of the EDD that could be off by a few weeks still. ...Read more
At 5w5d i was given an edd that was 16 days off the date that it would be if they used my lmp. Is that late ovul from irreg cycles?
Can't say.: If you haven't already ha d a pregnancy ultrasound get one as it will tell you what the age is of the baby. ...Read more
Hello I was given two different due dates from two different obgyn. One told me lmp was on nov 15 another told me nov 21. Would this make a difference?
Not really: All pregnancy dates are estimates, except that the conception date is known in an IVF baby (conceived in the lab). Pregnancy dating estimates have a range of plus or minus one week... which means November 15 and November 21 are "the same date" as those days are less than a week apart. ...Read more
Lmp was 4-27. I was given 2 due dates...2/17 on june 23 & 2/5 given on 8/12. What is my likely conception date range? Late ovulation?
By dates 5/2: I am not sure what the 1st due date was based on because by your dates (LMP) you would be due on 2/5 or 2/6. If the 1st due date was based on an ultrasound it is very reliable that early.Conception probably occured between 5/6 and 5/17. ...Read more
