I found out I was pregnant about two weeks ago. I don't know when my lmp exact around the 15-18 of November was my first day. I had unprotected sex with my boyfriend a good amount of days after , during, before lmp. My boyfriend and I got into a huge fight on dec 2 I slept with someone else two times that night he pulled out. What are the chances that it could not be my boyfriends? I feel horrible and I know it's my boyfriends but still have this thought in the back of my mind. Thanks

You have to tell them both because only god knows what day it happened... Doctors can only guess within a 28 day window.

You have to tell both... have a DNA test done after birth... They will both be thrilled to know.

Calculation of conception dates is an inexact science. The only way you can tell for sure will be with a paternity test AFTER the child is born.

No, you have no idea it is your boyfreinds.

How many times did you have sex ? That is the odds, 8 times with boyfriend, 2 with stranger, then it is 20 percent odds.

But odds mean nothing, if it was just one percent, it still could be the other guy.

There is no way to come up with an exact date, it does not work like that, even the best are give or take a week, and some up to two weeks.

There will just have to be a DNA test when child is born.
