birth control
"I was on Mononessa until the pharmacy changed their preferred generic to Sprintec. I never have acne and within days of taking the first pill I started breaking out. My period started 4-5 days before it was supposed to and I ended up having 10-11 day periods. On the previous pill I wasn't only having 5-6 day periods. This is the worst birth control experience I have ever had. I tried it for 3 months (mail order pharmacy sent 3 months worth) hoping it was just the first month, but instead I had 3 months of the longest periods of my life."
