On December 25th I had sex with my boyfriend. That night I took a home test to see if my lh was high, and it was. I am now on day 3 of my period being late. Two days ago I was in the shower and the water was hitting my nipples and it hurt SO bad. I have really bad cramps and diahrea(sorry tmi) I just don't know if I'll have my period soon or if I'm pregnant? Thanks in advance!
