birth control
"I been on evra patch for a year now, no specific mood swings no spotting, normal periods as 7 days, period only starts on 3rd day after removing patch and overlap by 3 days! Breasts have grown I might say a cup size. Some of periods I had very bad back pain some  I don't even feel ( so I don't think is anything to do with patch) 
I have not gained much weight and I think it's nothing to do with patch. If I eat like pig I get fat if and if I cut down on carbs I slim down."
