Yesterday, me and my partner have been involved in sexual contact without intercourse. A whole through, he noticed I was bleeding. I'm due to start my menstrual cycle in a week and under a controlled pill. The certain pill I take does mention there could be irregular bleeding between periods so just ignored it. When I arrived home, I started having pain around the vaginal entrance and now have a brown mucus-like discharge every time I pee. Once again I ignored it as I've read it. Plus just be caused by a cold, however, I've been to brush my teeth and noticed I spat out a fairly large amount of blood. I have checked for any visible gum bleeding but nothing could be seen! I then tried rinsing and I still spat out blood. What is wrong?
