I've been on the ortho evra patch for three months taking it regularly 3 weeks on fourth week off but this June I decided I'd keep the patch on for the forth week because I didn't want my period for the first week of summer. It felt weird having it on and I really needed to know if I was going to have my period so I put it on that Saturday but decided to take it off Monday night. So now it's Thursday and I usually have discharge but nothing and I'm really scared and unsure of what to do. I really do not think I'm pregnant could it maybe be that I only had that patch on for two/three days so it's still in my system? Please someone help me.
