starting birth control

Melody

-posted this in the other topic section too but just in case lol- so I took MAP 10 days ago and now I'm bleeding. it looks to me like my normal period but I also took MAP before where I had light bleeding 5 days after. I wanted to start the daily contraceptive pills and been told i need to take the first one on the first day of my period. do you think I should just start on the pill? my period is supposed to be due this weekend
