Oops, did NOT see that this thread had posts already. I posted in the other one.
Lyria-Sweety, have you been to the gyno for a checkup since starting BC? My friend had a similar experience...and I don't think it's your period "catching up," although I'm not a doctor or anything. She was bleeding for three weeks at a time because her ovary had a cyst on it or in it or whatev. She found out too late because she put off visiting the gyno for 5 months of this, and now she has very little chance of concieving. Not to scare you, but your post worried me a little...if you haven't had a checkup, get it!
