The waiting game...

5 dpo I had random light pink/brown discharge, which lasted two visits to the bathroom with slight cramping. Fast forward to about a week later, Nipples are so sore right now I can barely touch them, hardly any discharge and 4 days until AF is due, and my husband did not cum in me when we had sex but we started sex without a condom and ended with one on. Guess I'll wait until I miss my period to do anything. Anyone else experience these symptoms?
