Hi I'm pregnant but unsure as who my baby's daddy is and would like some opinions. So here goes I found out I was pg on 19th may, lmp was on 19th April. I had a scan today and told 8 weeks and 3 days, I had sex on 28/4 with ex then on 5/5 had sex with new boyfriend, who did I most likely conceive too? Please help..

As the dates are so close the only reliable method of determining positive paternity would be a DNA test, which is most safely conducted AFTER the birth.

Weeks pregnant and conception dates are estimates and are at the best ( and they are seldom at their best) give or take a week.

There is no way to ever know before the baby is born and a DNA test is done. If there was three weeks between it would be a much more educated guess but not this close.
