Hey, I took Norlevo after having an unprotected sex on the 18th day of my cycle (my cycles are about 39 - 42 days long), it was 11 days ago. I did manage to take it around 12 hr after the intercourse. I didn t really suffer any side effects and my period is due on 12th - 14th May. Is it normal that I m not bleeding and that I m not experiencing any side effects? I read that my period should come earlier, then, that it can come later, and in some places it says it can come as usual. Please answer! I m really worried!
