My last cycle was July 29,2015 and it is now August 28,2015 I have had send with my partner numerous times since then. August 5 or 4th I could be mistaken we had unprotected sex and he came in me several times. We had sex again August 14 and he came in me that day also and we recently had sex again august 21 and it was the samething. I have no signs of PMS i recently got treated for strep 4days ago but before then I was sleeping and eating irregularly I've also have early morning sickness and throwing up a few times with occasional diahrea but I'm thinking it's from the meds please help
