just don't know??

Samantha
So my period was oct 2-6 I had sex the 2ndbefore my period started and again on the 8th when I was off my period my app says I was fertile but my cycles are trying to regulate after coming off birth control so I can get on a different one. My husband and I had a baby he is 9months old now and we don't want another on for a few years I am worried cuz my stomach has been cramping and I have a ton of discharge coming out last time we had sex I was feritle and ovulated the next day. Any ideas on why my stomach has been so cranky?
