Hey, i've been on Yaz for 4 months now and just started a new pack a week and a half ago. During the first seven days you're supposed to use another birth control method, which my boyfriend and i did. One night though the condom broke, but it was pre-ejaculation. Just to be safe i took Plan-B because i'm paranoid about getting pregnant. I took both pills on time, and i've taken all of my regular birth control pills on time without fail. Yesterday though i started having bleeding and cramps like a regular period which has continued through today. Is this implantation bleeding or breakthrough bleeding? i could really use some advice. i'm very paranoid.
Thanks
