My regular periods date is 9 Aug 2021 after this on 17 Aug i took ipill after an unprotected sex and then on 20 aug another ipill but as a precaution after the protected sex then i got light spotting on 30 & 31 Aug 21 for 2days only. After this i feel bachche and leg paining as an indication of my menstrual cycle but i didn't get my periods yet. Is there are any chances of pregnancy? What does this indicates? How can i get my regular cycle? Kindly advise.
