Hi, It's Dr. C. Board certified Ob-gyne. I can help you today.

I'm sorry to hear about this confusion. Let me look at the dates. It will take just a few minutes. Then I'll get back to you with what I think

OB GYN Doctor: Dr. C., Board Certified replied 1 year ago

Ultrasounds are the most accurate way to tell conception date. If the ultrasound was done before the end of January, it's accurate to within 3 days. In that case, the most likely day of conception was November 7th with a range of November 4th through the 10th.

But because sperm can live for 3-5 days, sex as early as October 31st could have resulted in this pregnancy.

I hope this is good news. Please let me know if I can clarify anything or add details. I want to be sure you have the most helpful information for your situation.

Wat about sex from October the 30tg
Customer reply replied 1 year ago
my ultrasound was done the beginning of march
OB GYN Doctor: Dr. C., Board Certified replied 1 year ago

If the ultrasound wasn't done until the beginning of March, the error would be bigger. The range would be November 7th with a range of November 1st to 14th. With sperm living for 5 days, the earliest sex would be October 27th. So yes sex on October 30th could have resulted in this pregnancy.

Anything else?

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.
