... ahead and start my birth control bc my period had been late and I had been stressed out but to mention I had not had sex so there is no way Im pregnant but when I started orysthia it has been making me have cramping really bad, and on Saturday I started bleeding but it wasn't bad so me and my bf decided to have sex but used a condom and it was my first time it was just like spotting but today it's heavy bleeding like my periods usually are. does anyone know what could be going on?
