So my period started 2 days earlier than usual, was abnormally heavy for 2 days and then today I just have some light spotting and I am extremely nautious with stomach pain that might resemble really light cramps I guess. I started birth control pills 2 cycles ago but I haven't noticed anything abnormal since I started. About a week ago, I took it a couple hours late because of a nap and had unprotected intercourse that night. Could I be pregnant?
