Ortho Tri-Cyclen Lo
"This is my first time using birth control pills, and it was for 2 reasons: preventing pregnancy and reducing forehead acne that always worsened around ovulation. 
I've been taking Tricira Lo (generic brand) for the past 7 1/2 weeks. 
Initially, I found myself more tearful, but that settled down after 4 weeks. I had one instance of a headache & nausea during the first 4 weeks; haven't experienced either since.
There's been ~5lb weight gain and some increase in breast size (not by a full cup though). 
I haven't noticed a significant difference in my forehead acne. It's still an issue for me, especially during the 3rd & 4th (placebo) weeks of the pack. I think this may be because hormonal acne more often presents on the cheeks/chin."
