Can sumone help me my ex and I had sex on July 1 and then on July 4 I got my period but then on July 27 was with current boyfriend and now I'm pregnant is there anyway it could the my ex? Help!

Not likely that it's your ex since you had a period after you had sex with him.

But, not likely isn't for sure. You'll have to have a DNA test done once the baby is born to confirm who the father is.

Sex right before period can have period and still be pregnant, so it is possible to be first man.
But this is far enough apart ( over 3 weeks) that when you do the ultrasound and determine how far along and estmate due and conception dates, it should give you a good estmate.

Except if they come out with a concepton date of like the 15th or something, in which case it could still be either.

A lot of stuff tells me I conceived before the 27 but how is it possible to be current boyfriend if that's when I was with him! I guess that's what confuses me

Yes and that is what happens with 1000s of pregnant women each year. When they have sex with more than one partner within weeks of each other ( heck we get some here within days of each other) there is just no way to be 100 percent sure of the father till the child is born and a DNA test is done
