So I ovulated on the 18th and had sex on the 20th. We used a condom but when he pulled out , we realized it was really broken. I took a plan-b pill the 21st. It is the 27th (a week later) and i am experiencing a heavy dark red blood discharge and my lower abdomen hurts and feels somewhat swollen. Also, tmi but I “went number 2” more than I ever had today. Could this be caused by the plan-b or is this early symptoms of pregnancy. Please help.
