I took ortho tricyclen lo for 3 months, and then stopped. I didnt have any side effects except decresed sex drive.

My question is...I stopped taking the pills almost a month ago, so I should be getting my period within the next week. Usually my breasts get tender right before my period. However, while on the pill the have become larger by about a cup size, and now they are more sore than normal. It's been for about 3 days.
Pregnancy is not possible (haven't had sex since before the pill).

Has this happened to anyone else? It helps if I wear a good bra, and I usually wear 2 sportsbras to the gym now. It's not constant pain its just once in a while.....
