Hello sir/ madam im 20 years old and I had sex for the first time on aug 8, 9 2015, I took emergency contraceptives on aug 10, and another dose 12hrs later and 3 rd dose another 12 hrs later, my periods had to come on aug 13, but there is no periods still now it has been six days and im still not getting my period. I had a mild spot on aug 13, and a scanty bleed on aug 18,. My shortest cycle is 26 days and longest is 31 days. My last period was on july 13. Aug 8, 9 were my extremely safe periods, is there chances of me to get pregnant? How long can my periods be delayed? why did I get a scanty bleed yesterday?
