I take Junel fe 1/20 birth control pill at pretty much the same time every day. I have been having lots of sex without any other protection. I have also been on 3 different antibiotics in the past month which I’m not sure if they affect the pill or not. I am suppose to start my period in a few days but I have been having lower cramping at night, breast tenderness and nausea up to a week & 1/2 before my period which is not normal for me. Certain smells have been bothering me & I am also prone to ovarian cysts. Could I be pregnant? My periods have been normal if not heavier from taking the pill
