My boyfriend and I Just started having sex. I have been on Ortho Tri Cyclen Lo for about 4 or 5 months now....i am a bit worried about it's effectiveness though. I am 5'7 and about 180 lbs..but not really fat? I just have a lot of muscle, maybe a little chubby around my midsection, but I don't look wayy overweight. I heard though that the pill can be less effective for women who weigh over 150 lbs. or something. I asked my doctor about this, and didn't get much of an answer..just 'take the pills correctly and i should be fine'. Also since they are the low-dose pills I am worried. I take them everyday at the SAME time, and have very regular periods. We used a condom as well.
Am I playing it safe here or should I be worried about the effectiveness of the pill I'm on?? How are any of you other women who are heavier and on the pill? Is it working for you?

Thanks so much.
