I got off my BC the beginning of December.. had my period Dec 4-10. My boyfriend and I have been together 4 years and don’t use any protection currently. Usually every time we have sex he cums in me but hasn’t near my ovulation timing. I’m currently 3 weeks late on my period and have random cramping and bloating like I’m going to start my period but then it goes away after a few hours and nothing happens. I’ve taken a test that came back negative so I think I’m just off my cycle because I stopped my BC. Opinions??
