Hi, I am 20 yrs old. I had unprotected sex on 2nd March and took i-pill before 24 hrs. My period date is 11 March, I took pause mf on 8th March and stooped taking it on 11th march. Till date my periods has not come. (16march). I have started period pain from 14th March but it has not come yet. Am I pregnant? Or is it because of doses?
