The last time i had my period was july 28, recently my body has been feeling different i get more hungry and wake up in the middle of the night extremely hungry so hungry i even dream about it, i dont know if it has anything to do with whatever is wrong with me. And yesterday while having sex with my boyfriend i started bleeding and it wasnt just a little bit. He told me i could have miscarried but i dont know if i was pregnant in the first place. What should i do?
