I hope I don't get judged. I had sex on the last days of November (dont remember which one) with some guy and I got my period around December 4-6 then I got back with my partner on December 21 had sex with him I missed my period on January and now I'm pregnant my due date is September 17 2014 I'm stressed out I don't know who's the dad if anybody could help me answer this it will be great!

If you have only had sex with one person since your period, that person is highly likely to be the father. While its not impossible the person you had sex with in Nov is the father, the chances are so small I wouldn't worry about it.

Unfortunately, calculating due dates and conception dates is an inexact science so we can't tell you for sure. But if you are due in mid September conception likely occurred in mid December.

It is a very high chance of being the man in December, but there is no way to be 100 percent sure, it would be best to do DNA test once child is born just to be certain.
