On July 20, I had unprotected sex.  On July 25th, I started to have a brown sometimes red discharge for approximately 10 days.  I have had negative HPT.  I went to my general doctor on 8/22.  I was told by the nurse that my temperature was a bit elevated and my pregnancy test came back equivocal.  Since then, my breasts are sore, I have hair around my aerolas and bumps on my nipples.  I have not seen a period since July 25 and that was not regular. My doctor told me that I had to retake the pregnancy test so I took it on the 4th of September, that came back negative but my period is still not here and my breasts are still sore.  I am premenopausal.  Can someone share their insight
