December 09 was the last time I had my period. I live with my boyfriend so we have sex at least 3 times a week. I left town on December 26th with out him to visit family. On January 3rd I had a one night stand unfortunately (I refuse to tell my boyfriend unless I have to) I took my first pregnancy test January 7th and it came back negative I then took one on the 12th and it came back positive.. and again a positive test on Jan 13. First response 100hcp.

I just wanted to know if the father of my child is my boyfriend or is there a higher chance of my one night stand being the fahter? I need to know asap Im freaking out.
