Just curious?

So on July 24th I lost my virginity ,we used protection and he never came. On August 3rd we had sex again we once again used protection except he came and pulled out. My period was due the 25th and it's still not here yet and my boobs are sore but I'm not getting any cramps that would be another sign of my period coming on. I don't think I'm pregnant but it's been a worry in the back of my mind.

Also I have a yeast infection so I don't know if that would delay or affect my menstrual cycle.
