I'm on birth control, so I don't know if I am pregnant, especially since I think I take it regularly. Anywho, my period normally starts Tuesday or Wednesday, always has. It is Thursday night and I've had spotting- pink and brown- for 2 days on and off and it seems to have stopped altogether today. But it was very light. I know it's not my period because I get extremely bad cramps and heavy bleeding. Everyone once in a while I feel a sense of nausea, and I had a small pain below my belly button an hour or so ago. I also am having frequent urination, more than normal. My period is never late so I'm kind of worried... Plz help if you can. I know it's not much to go on.
