After being off my birth control for about 10 days I started taking it again and I had some bleeding. My doctor said this would most likely happen. I bled for about a week. The area down there started getting a little itchy and irritated because I wear pads. A couple days ago the dull achy feeling came back and I've had pretty light bleeding. Today I noticed blood coming from my clit. It wouldn't show while urinating but it was in my underwear and on the toilet paper. It had also been a little itchy and I had sex in the early hours of yesterday morning. It any of this something I should be really worried about?
