My period started 3 days after surgery, even though I was on birth control and it wasn't time for it to start yet.....how fun!!! NOT!! At that time I was using nuva-ring.
Then in late July, I started new birth control and during that had a normal period but haven't had one since then...had a pregnancy test at the beginning of August during my period (a requirement to get an IUD) and haven't started yet....I'm debating getting a pregnancy test, even though I know I'm not..... but I am guessing that between the surgery, weight loss, and new birth control that my body is thrown off and is now whacky....I'm not sad about lack of a period, though!!
