I have been on birth control for three and a half years. I had unprotected sex for my first time and took my last pill in my packet that night. I went to renew my bc and they said it would take three to five days. I had old birth control with me and took that the next day. On the third day I got a plan b pill and took that as well as the old birth control that night. On the fourth night I got my regular birth control back and have been on that since. It has been two weeks since I had unprotected sex and I am still really bloated. I am feeling discomfort in my lower stomach. My boobs don't hurt as bad as they used too. I am really hungry lately and have been urinating a lot more than usual. It doesn't hurt and I don't have blood. Is it a urinary tract infection or could I be pregnant?
