I had unprotected sexual intercourse with my boyfriend the night on (18.12.2010 around 11 pm)but he went out of me when he was coming, but just in case I took NorLevo pill the following morning (around 10am). But my problem is different now, we had unprotected sex again the following night on 19.12.2010 around 24:30 but this time he camed in me (it happened so fast ) I want to mention that I'm on my 4 day of my period, should I take the NorLevo pill again or what should I do to stop getting pregnant? We often have unprotected sexual intercourses but we are careful too, this is the first time that he come in me till the end. I'm 21 years old.
