acne
"Not sexually active, so I can't tell how it helps in pregnancy prevention. It did stop spotting in between periods, but it destroyed my skin. Particularly along my jawline (jawline acne is typically hormonal), my skin broke out the entire duration of using Trinessa. It was the hard, painful acne that left behind dark marks when they had run their course. I stayed on the pill for three months to make sure it was a the pill causing the acne, and it was. During the placebo pill week when you get your period, my skin would clear up. Until I had to start the pill again, that is. Beyond that, my emotions were so out of whack on this pill that I was constantly on the verge of tears when I am a silly, easygoing girl who is extremely positive."
