birth control
"I was on this pill for the past 5 years, and I really really liked it up until recently.  I barely ever get a period which is awesome, but i've been noticing the past year or so that my headaches have become almost daily and it's shooting pains above my right eye, my hair has started shedding so bad it's really disgusting and my boobs always feel so sore, even from just wearing a bra. I think my body has changed and the pill does not work the same way anymore."
