I'm 19 years old on Feb 8th of this year me and my bf had sex though he never entered my vagina he ejaculated outside on a piece of cloth. We weren't sure if the cloth had touched my vagina so to be on a safer side I took I pill after 4hrs. Later on got my periods on 23rd Feb with brown bleeding for 7days. Now I'm late on periods for 8days. I'm scared if i am pregnant please help me.
