Hi, I had unprotected sex on the 4th, I had light spotting the next day, and throughout the week I was feeling very dizzy and nauseated, and had cramps in my lower stomach. I got what I though was my period on the 8th but I only lasted a day. On the 11th the pain in my lower stomach was getting worse and it hurt to pee, and so I went to the hospital and they said I had a urinary tract infection and gave my anti biotics. So getting over the burning sensation around the 16th, I was still feeling very nauseated, I was passing gas a lot more and peeing a lot more too. I found I was wanted to eat everything. I was just getting so hungry all the time. And still am. Today, the 20th I ve been having really bad back pains and still feeling very nauseous. I m still peeing, passing gas and eating a lot too. Could I be pregnant? Thank you.
