i and my boyfriend had unprotected sex on the 7th and 8th of april. my period was meant to come out on the 9th but didn't. For fear of being pregnant, i took postinor2 on the 10th at about 4.30pm but had sex with him on 11th at about 12.20am. Pls help me i've not seen my period yet, am i pregnant? If yes, what should i do?
