birth control
"I was on Seasonique for 2 years. Seasonique started out as an okay form of birth control. It took my body a while to get used to it (probably about 2 packs, so 6 months). When I did get used to it, it was great. But then the problems started. I've never had acne or even bad pimples and my face started to really break out. Also, I don't know if my body got immune to the birth contrl but after a while, my heavy periods came back as well as the cramps. 
Also if I ever forgot to take my pill and had to double up, I would get really sick. Overall, it started out great, but the effects were not long term. I've gained 15 pounds and my libido is very low and I'm very dry when having intercourse. Also, as mentioned earlier, it gave me very bad acne."
