Paternity worries

[Confusedmum18]

My 12 week scan gave a due date of 20 May 2019. When would be the earliest possible conception date? I made the stupid mistake of having a one night stand on 10 August, is this too early for a possible conception date?

That does seem too early to me. When was your last period? Was that the only unprotected sex you had after your last period?

I’ve been through such a tough time around that time I didn’t write my period down. I may have had one from 13-16 August, but I simply can’t remember. I am so so worried

No it wasn’t I got back with my partner on 17 August

My 3rd was due 13th may (born 20th) conception was 6-13th August

Actually the first two weeks of pregnancy you're not actually pregnant so add 2 weeks into my dates #dumbmoment 🙄😂

So what would do been your conception dates? Are you saying 10th we do of been to early?

See the website here: www.weeksduringpregnancy.com/calculators/duedate.php?month=8&day=13&year=2018

It puts you at 0 weeks pregnant (ie your period) on 13/8/18, which roughly matches what you expected. It puts ovulation at about 27/8/18. Sperm, realistically, could live an absolute maximum of 7 days, and the egg for 2 days, so conception can really only happen from any unprotected sex you had between 20/8/18 and 29/8/18. 10/8/18 is way off. However, scans are not absolute, and it is possible that the scan measurements were not completely accurate. The only way to be certain is a DNA test once baby is born.

However, going by those dates, and the fact that you think you had a period AFTER the one night stand, makes it very unlikely that he is the father, and it is more likely to be your partner.

20th if dating scan was right but by the day he was born the 27th
