I had unprotected sex 5 weeks ago, I had my period for 4 days last month and last month I had a normal period. I went to my doctor for a check up and she said since I’m on my period I’m fine. I started birth control Wednesday. My boobs have felt heavy the past few days, and then today I am having to pee like crazy! Is it the birth control? I’m on the pill or do I need to take another test??
