birth control
"I'm 22, normal weight, healthy. I was nauseous and broke out for the first week. My boobs were basically always tender, but they also swelled (I'm like an A cup, so I saw that as a plus). I have always been an easy-cryer, and it did intensify that. I've always had a low libido so I don't think changed MUCH (although my libido went way up after getting off of Sprintec). 
I was sad to have to get off it because I had such minor side effects, but the issue I had was bleeding for 7 months. It was light- I went through about 2 panty liners per day and didn't need to sleep in anything- until the last week when I got fed up. I bled so much that I was blacking out and feeling sick. I stopped cold turkey and got headaches but the bleeding is over!!!"
