So they base it on your LMP, and 40 weeks later is when you are due. They can change your due date after you have an ultrasound in the early weeks to tell how far along you are by measuring the baby. So it is confusing, but in the end it turns out right.

If her first ultrasound was at 5 weeks, it will be the most reliable for working out a conception date.

When I asked the Dr the conception date he said July 9, 2014 and when I do the conception calculator wih both edd the earliest I could've concieved is June 28, 2014. I had my period starting after June 10 and ending before June 21. Is there any way I could've concieved prior to my cycle and the Dr/ ultrasound give an estimated conception date off by 3- 4 wks?

I had irregular periods so i couldnt use that as a measure.

Yes.

http://www.babymed.com/conception-calculator (select due date instead of lmp and put in March 14, 2016) Based on the due date, she got pregnant sometime around June 17-22 and is currently 11 weeks. She is either lying about how far along she is or when she is due.

More likely your boyfriend's; it sounds like you were already pregnant when you slept with the guy a week ago. Get an ultrasound about your fifth week from when you think you might have conceived, and see what they tell you about your estimated due date based only on the size of the embryo and its development. Tell them that your periods are very irregular and you can't judge when you ovulated by when your last period was.

I had an u/s done 13 days ago to date my pregnancy....I was due for my period on 12/27 but it never showed.....I did not get a + pg test until 1/9( it was the 1st day it came up faint + b/c I tested the day before that with 1st am urine and it was negative).............at the U/S they dated the baby 7wks....so based on 7wks I figured my conception was around 12/24.....my question is how they calculated my due date....

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.

I had two periods last month. Which period do i use to calculate my due date?

Conception calculator gives the following, but it depends on how regular your cycles are and what length. If you ordinarily have 28-day cycles, here is what it projects: First day of last menstrual period: November 20, 2012 Probable date of ovulation: December 4, 2012 Possible dates of conception: November 30 to December 8, 2012 Due date: August 27, 2013 (40 weeks) A lot also depends on how you got your due date. Was it by ultrasound?

Here is what the conception calculator says based on your due date. First day of last menstrual period: February 19 Probable date of ovulation: March 5 Possible dates of conception: March 1 to 9 Due date: November 26 (40 weeks) But it also sounds from your information that you've seen a conception calculator or you wouldn't think you conceived on March 5.

I just want to know when did u concieve? My first ob told me my due date is feb 25 based on my early ultra sound,my second ob says march 2. Im confuse..! first day of last lmp is may 21 or 22.and im having a girl....

Especially if the ultrasound was relatively early in your pregnancy, you can plug the due date into a calculator for an approximate conception date.

Here is what the calculator says about a due date of December 14. All told, nothing adds up to April 6 as a possible conception date.

Until you get an early ultrasound that tells you an estimated due date, you have to assume that either guy could be the dad. Some women don't ovulate on the schedule provided by an ovulation calendar and pregnancy calculator. (All an ovulation calculator tells is when an average woman might have ovulated.

Sorry, i hit send to fast Based on my ovulation date and not my last period Sept 22nd, i wonder what the due date would be. Would that be Oct 4 + 266 days?

Your conception week would be around June 8th. If you google "conception calculator by due date" you can enter your due date and your conception, ovulation, implantation, LMP come up. They're approximate, of course.
