I have been on the 4 months going on 5. i may have gained a little weight but just water weight. My skin has cleared up and i am not getting the PMS breakouts anymore. I just turned 29 and still get acne so anything that helps is welcome. however i have been noticing slight headaches here and there. i typically don't get headaches and from what i have read on these blogs the ring may be to blame...other than slight weight gain and a headache or two it's been good using the ring. i also don't get ravenously hungry before my period anymore which is a blessing, i would eat anything and a lot of it-lol! i am going to be paying more attention though, and come to think of it i have noticed been tired and i workout a lot so i usually have tons of energy. tough call, i guess every birth control method has draw backs.
