birth control after birth

Kara
I started taking the pill just on a Sunday. I wasn't aware I had to wait for my period. I started bleeding a week before sugar pills. Now I'm on day 2 of sugar pills and bleeding heavily. I've had some clits too. Not huge by any means but gross and enough for me to be worried. I know birth control can cause irregular bleeding and since I started the pill so randomly I guess that could really be throwing me off. This is my first "period" since having my son 8 weeks ago and it's just freaking me out. I'm going to call my ob back, but does anyone have any experience or any advice? Thanks!
