Hi my name is Samantha and I m 16. I had unprotected sex on Saturday last week but he didn t finish but could I still get pregnant from pre cum? I have been worrying and my period is not due until next week. 3 days ago I had cottage like cheese discharge in my underwear for about a day. The next day I got blood. I thought it was implantation bleeding but it isn t what implantation bleeding is described to be, it looked like my period, dark rich red colour with a few clots. The only thing is that today it has finished, it s the third day, it normally lasts 5. Please help! What should I do
