Has anyone had this before? Tmi

We have been trying since June. Had a chemical in June/July. So far no luck. I have been off birth control since may and my periods did change j just not very much. I started shooting in the second and af was due on the 3rd. Spotted on the 3rd. And ended on the 7th. But it was inconsistent. It would stop and go. It was pink red and brown at different times and was much much lighter. I think I only bled medium flow for a few hours. Normally it is consistently heavy heavy the whole time. And since it ended i so feel like im on my period. Breasts hurt. Bloating uncomfortable boating at that and cramps. Even been nauseous. And i absolutely hate seafood. But I decided for dinner I really wanted fish. Got it age it and loved it. I dint know wth us going on. Anyone had this happen before?
