Okay so I had protected sex with my bf on August 19 and my last period was July 24. Normally I have a 42 day cycle and I'm almost 2 weeks late. I took a 2 tests when I was a little over a week late and both were negative. I haven't shown any pregnancy signs other than my back aching which also happens with my period. The condom didn't break or slip. Am I pregnant and if not what's wrong with me? Please answer
