i I took postinor on Jan 31 after having contact with my bf and follow the instruction prior on that I took Diane pills (contraceptive pill) also on Jan 4 may menstrauation is Jan 28 my last menstration is Feb 3. Until now my I still don't have menstrauation is it cause by postinor. I just feel a bit cramping on my stomach like as usual period and eating much but i crave any foods. Other than that I don't feel anything like early sign of pregnancy but I'm still worried and scared to take pregnancy test. Hope u can help I'm a bit anxious. Thank u
