My partner and I , we did unprotected sex on 18 Aug and my partner eat I-pill medicine on 20 Aug. she ate i-pill under 48 hours and the problem is that she expects to gets periods on 20 Aug but yet she didn't get periods and today 21 Aug there is also no symptoms to get periods. Last month she gets periods on 23 july and according to 28 days of periods cycle she would get her periods on 20 aug or 21 aug. We heard that if a girl gets her periods then she can't be pergnant. I am worried is she
pregnant or not. Because she doesn't get her period on her expected date. Help me to understand this. If she is pregnant than what should we do to prevent her pregnancy.
