I had protected sex January 7/8 (condom and boyfriend pulled out before ejaculating) and so for some reason I thought I was pregnant and took a test after I had gotten my period on Jan. 20/21. I was still paranoid so I took more tests and they were all negative. In February, I got my period again. Took 2 tests for the heck of it, negative, in March I got my period this week, took 2 tests and they were negative too.

My period has been relatively normal, with heavy days and clots, and I did test negative. I have this hard area on the left side of my belly. I'm not sure if it is my abs or not (I am pretty thin). When I tighten my abs this area becomes a lot tighter.

So, what's the likeliness? Does everybody have this hardness on their left/right side? Should I be worried? Thanks!
