birth control
"I took this pill for 2.5 years and it was pretty good. When I first started the only negative side effect I had was nausea 24/7 for about 6 months but it eventually went away. I had to switch to a higher dosage because my PMS symptoms like hormonal breakouts before periods came back after about two years on the pill. However, I have regular sex and I never got pregnant! So it does its job"
