Hi there, I took postinor2 in January and February and during these months, I had my period normally as expected. There was no side effects. But up till now, I haven't seen my period for March. I have been feeling the menstrual symptoms though but am still dry. I just did a pregnancy test today and it was negative. So I want to know, could this also be as a result of my intake of postinor2? Am kinda worried because I am already 3 weeks late. Thank you
