I'm trying not to go crazy.

So I had sex on January 14 and we used a condom but it broke. I didn't see nothing really in the condom, like cum. I was supposed to get my period the week after but it never came. I took a pregnancy test it came out negative.  I have little cramps here and there, thinking my period is going to come, but ITS 11 days late now. I'm trying to wait patiently, but it's kind of driving me crazy. Idk if it's cause I'm getting fat😔. Idk what to do
