So about two months ago I missed a pill and had unprotected sex the same night. I panicked and took a plan b. After more research I found that I didn't need to take the plan b. But this month and last month I've bled in the middle of my birth control pack. My cycle right now is very similar to when I first got on the pill. Is this all a side effect of taking plan b? Is my cycle going to get back to normal?
