Go to your calendar. Go to Sept 12th. Count backwards 6 weeks 4 days. I did it, if I'm right guy B is the father.

You conceived the day after me, August 12th. You don't count the first 2 weeks cause you're not pregnant. They count from the first day of your last period and you ovulate between cycles so you got pregnant 4 weeks and 4 days before your ultrasound.

I have an app on my phone, so I typed in what your estimated due date is and it says you conceived Aug 11th. It's pretty accurate. For the best results to find out, wait until your next doctor appointment and ask.

You ovulated sooner. Completely normal. And sperm can live in the vagina for 5-7 days after you have sex. Even precum. Guys b is definitely the father. The earlier ultrasounds are the most accurate because after 14 weeks, babies start too grow at di

My last period was the 26th of july, which makes me due May 2nd. I know for a fact that I had sex on the 8th of August, and conceived on the 9th. If your periods are very regular, then you should have conceived on the 11th of august since they told you you are due May 4th.

but they fact that you found out you were pregnant on the 20th means that you had to have ovulated sooner.

It sounds like you are just going to have to be honest with the guy and let him now you aren't sure. Or maybe there is some story you can come up to get a Dna test without looking suspicious.

What acline said^^ you can't get a positive hpt until at LEAST 7 days past ovulation. Most are 10 days or more. If you went by your actual period, you wouldn't have been able to because the egg wouldn't have implanted yet to start producing hcg, the hormone hpt's detect. Even first response 5 days sooner is only 10 days past ovulation.

I'm sorry, I was doing the math in my head before. I just wrote it all out and you ovulated later than average, but still normal. Ovulation is usually directly in the middle of your cycles. From the start of one, to the start of the next.

Also, if I came off brash or abrasive in any way, I apologize. I do know a lot about conception and was only trying to help.

Doing by your due date, which is based on the development of the baby, ovulation was may 18th. Regular period or not, babies grow at the same rate up until 14 weeks. Your actual period doesn't matter at all. It's baby's development.

If your period is very irregular, that would explain why the (estimated) first day of your last period (on the conception calculator) was not where you expect it to be.  Conception calculators assume a regular 28-day cycle and just plug the number in.

Go with the measurement the doctor took with your ultrasound in your 6th week.  Ignore if counting backward does not line it all up with your actual period, especially if your periods are irregular anyway.  An ultrasound for dating is more reliable than the first day of your last period if you have the ultrasound early.

Sorry, I was thinking of the original poster of this thread, who had an ultrasound in her 6th week.  An ultrasound in the 11th week won't be more than two or three days off at the most.  Same advice still stands.  If your period is very irregular, that would explain why the (estimated) first day of your last period (on the conception calculator) was not where you expect it to be.  Go with the measurement the doctor took with your ultrasound in your 11th week, over the date of your last period.  The doctor saw and made a measurement of the actual baby.  Especially if your periods are irregular, don't worry if counting backward does not line up with your actual period.
