I've really haven't had a problem with this side effect wise but I noticed my last period was only four days and then I got it a week early and haven't stopped bleeding for 14 days now it almost feels like I had two periods back to back, before my scheduled period it had lighted up but once I took the patch off for my fourth week I started bleeding extremely heavily again. I've been on this for about three months now. So is it just my body getting used to it or what? I'm just concerned with how much I'm bleeding and for how long.
