Hi, I had unprotected sex on 19 december with my boyfriend. I took postinor 2 within 48 hours after sex. And the second tablet after 12 hours of the first tablet. My next period was expected to be on 27 december. But I'm start to worry if my period will late. I want to know whether my period will be late? And how late it is? I dont want to get pregnant, and I am so worry right now.
