My last period was july 4th threw the 13? Was a really weird one to.. Well I'm currently going on 2 and a half weeks late? And I totally missed a period for June. the last time I had sex was in may right before my period. But now my boobs and nips are very sensitive and itchy nips (weird). Feeling bloated and my low stomach feels tender to the touch also having dull pains in lower stomach and back. I just find all these things going on with my body weird. If any one has any kind of idea or thought of what might be going on please help
