ive been on ortho evra for almost 2 yrs now. I recently started sleeping wit an ex again. we had relations while I was on my week off last month ( so no patch was on me.) I started my new week on the day I was supposed to. I was supposed to take my patch off this last week but instead I put an extra patch on when (4th patch on my week off) I haven't bled at all during this past week. I took off the 4th patch today (sunday) so my question is if I didn't bleed last week n I don't bleed this week could that mean im pregnant??
