I'm currently pregnant. My cycle was a very regular 28-29 day cycle... I had a period tracker app on my iPhone and I would get my period on the very day I was suppose to monthly... the month I got pregnant I had 2 partners. 1 is my boyfriend whom I have sex with everyday using NO condom and pull out method... I had a 1 night stand 6 days before I was suppose to get my period (WITH CONDOM).. I also checked the condom after by squeezing to make sure there was no holes in it... what are the chances of the baby being my boyfriend ?

The chances are pretty good that it is your boyfriend, but not 100% since there is no form of birth control that is 100% effective. You will still have to have a DNA test done after the baby is born to determine paternity.

Chances are it is one of them, and it all depends on the sperm count, the fertile days, and more. ** often just luck, (good or bad) the issue here, is you are cheating on boyfriend, and pregnant, so you are not in a good relationship anyway.

But, there is no way to know, who the baby belongs to, it can be either, You will have to get a paternity test when child is born, there is no other way to tell. Conception dates are only estimates, so no way at all to know, till child is born
