I have been on birth control for a month when i first got it my mother said that i could still get pregnant because the pill is not effective the first month but i still had unprotected sex. Because it seemed like it was effective because it was causing my hair to fall out and me to have bad headaches so i got tooken off of it i was suppose to be going to get another percription but not until my next period the last time i was on the pill i was on my period and i have been off my period and off the pill going on 2weeks and i'm starting to feel funny but not pregnant not to mention i have'nt did nothing since so why do i feel that way and is it possible.
