Is It Possible To Take A Best Guess On When Intercourse Might Have Happened?

default
Posted on Wed, 15 Jan 2025
Question: I have an ultrasound scan of my pregnancy - trying to figure out the likely day I had intercourse to understand paternity.
I don't remember the last period I had. I had a nuva ring I should have changed on the 21st of XXXXXXX but I forgot.
I do have however this a scan taken from 2 days ago I can upload - with all the measurements.
Is it possible to take a best guess on when intercourse might have happened if I share the scans?

the dates I had intercourse are:
- partner 1 - 4th of Feb and before in XXXXXXX (don't recall but maybe not full ejaculation inside)
- partner 2: 13th of Feb (don't recall but maybe not full ejaculation inside)
- same partner 2: 20th of Feb (full ejaculation inside)

Your days of intercourse have almost 7 days gap between them. You can share the ultrasound scan reports and the approximate date of conception can be calculated to find out the paternity.
