I tried skipping my period using the Ortho Evra patch by just starting the next round of patches without skipping a week. Instead, I just delayed my period a week and then my period lasted for two weeks! When I was done with those three weeks, I skipped a week and had only light spotting. Now I've gone through another three weeks and took my third patch off to start my period. It's only been two days since I took it off (Wednesday) but I haven't gotten my period yet. I'm concerned that this messed up my cycle and I could have gotten pregnant when my boyfriend and I had sex two weeks ago.
