19 Days Late, BFN

Tori

I have been pretty regular for a couple of years now, and on and off the pill. I was supposed to get my period on June 16th, but it never came. I had sex on June 3rd, using the pull out method. I have no signs that my period is coming and have been getting stomach cramps and nausea at random times throughout the day. Has anyone ever experienced this issue??
