... so without looking at the directions or anything I did. 2 days later I had sex with my boyfriend and he didn't pull out. When I actually did read the directions it only gave four different places to place the patch at. So on the second week I placed the patch on my arm. Then the third week I placed it on my lower right side of my back and two days later (today) I woke up cramping and went to the bathroom, and there was light blood in my panties. I shouldn't be starting my period until next week, I'm very confused. Can someone please help me?
