My G/F of 2 years just got the on the pill. Ortho Tri-Cyclen to be exact. Shes been taking the pill 3 days (got off her period 3 days ago). Shes taking the white pills (if that matters). How long before this stuff is fully effective? How safe is it? In my mind it just feels weird to think of going all the way without a condom. Someone give me a rundown of the basics.
