I need help

Michelle

I had a miscarriage on the 18th(Chemical pregnancy) and I havent felt very good past few days. Yesterday I was throwing up and today ive been feeling very nauseous and having awful headaches. I don't think its pregnancy related bcuz idk how fast that could happen. I mean we have had sex alot since ive stopped bleeding and I stopped bleeding on the 22nd. I'm just curious on what is going on.
