So my last period was 6/16. I had sex with one guy 6/23. Then i got back with my boyfriend 6/26 and we had sex pretty much everyday up until 7/4. Is there any way the guy i was with 6/23 be the father? I really hope not. Please help and respond in any way. I did those conception calculators and according to that my boyfriend should be the dad. But again I am not sure please help.
Yes it is possible that either guy is the father.
It all depends upon when you ovulated. That can't be determined after the fact. Disregard what any calculator will tell you they are only approximate.
Normally you'd ovulate SOMETIME between days 11 and 16 of your cycle. You had sex on day 7 with "one guy." Sperm can survive up to about 5 days. That's the overlap.
There is a chance, it's small but it does exist.
You'll need a DNA test to confirm paternity. They can be done before birth.
