Question
Is it possible to get a positive pregnancy test only 2-3 days post conception? My LMP was 4/16 and my positive test was 5/17.  I had three first trimester u/s.  They measured 7w3d on 6/10, 10w3d on 07/01 and 11w4d on 07/08.  Could I have conceived 5/14?  My other conception possibilities align with the likely 5/1 ovulation date, but I'm worried that I'm wrong.

Answer
According to both your LMP and all three first trimester u/s, you definitely conceived in early May.  If your two possible conception dates are May 1 and May 14, then you conceived May 1.

There is no possibility of a positive pregnancy test only 3 days after conception.  Pregnancy tests measure levels of hCG, and hCG starts to be released when the embryo implants itself into the uterus at 6-10 days, so there is no way you would get a positive pregnancy test before then.

You definitely conceived May 1.  There is no possibility that you conceived May 14.

I hope that sets your mind at ease!

Sincerely,

Childbirth
