"i was on the shot for about 3yrs but decided to change to a birth control, and my doctor recommended tri-nessa since i had mild acne. so i started taking it and i have to say i love it. my period comes at the same time every month, no pregnancy scares and i often have sex unprotected. my acne cleared up. the only side effect i had in the beginning was tender breast, and being a little emotional. after it went away. i take the pill at the same time every day. so i highly recommend to everyone."
