There was a chance I could of been pregnant , my period was due on the tuesday and it didn't come until Wednesday night. They were very heavy(I usually have heavy periods so it was nothing new) until friday they became quite light. Its now Saturday and the bleeding has stopped. They usually last 5 days. Is there still a chance I could be pregnant ? White discharge was coming out of my right nipple a week and a half before my period was due and I was getting cramp earlier than usual too. I'm only 18. Please help
