I experienced bleeding immediately after having sex. This was outside my monthly cycle which usually starts on 20th of every month. I had also condumed emergency contraceptive pills a week before this incident. The bleeding is accompanied by a stomach that feels tight and tensed. The bleeding is also of medium flow which requires changing of pads every 5-6 hours, and this is the second day of such bleeding. The bleeding also seems to be without clots or impurities, very unlike menstrual blood.
