Hi, last 30th April in the evening we had sex, without protection. After sex by 2 hours time I have taken Postinor-2 (two tablets together). As per my previous experience, I was having little bleeding like period for one or two days after taking the pills. This time since a week I have not get any bleeding or spotting. I am really scared of any unplanned pregnancy. What I should do now. Really appreciated your advice. Thank you.
