Hi, I had unprotected sex two months ago. It was the first time for both of us and he did not come inside me. I took the norlevo pill one hour after intercourse. I had my period normally after that. But now my period has been very late. I had some menstrual like bleeding for two days but it was very little. I did a pregnancy test and it was negative. I have no signs of being pregnant, no morning sicknesses or sore breasts. I am really worried of being pregnant, I moved to another country just a few weeks after I had sex and I live alone at a boarding school in a completely new place. I ve talked to my school nurse and she said the chances of being pregnant are minimal. What do you think?
