I had unprotected sex in mid of feb, and had taken an i-pill after 2 hrs of it, i missed my periods which were due on the 7th of march, so a friend suggested takin sysron-n which i took for 5 days 2 times in a day which i stopped takin on 22nd, I started bleeding on 25/03 and it lasted only for 2 days and the flow not so heavy, usually my periods are heavy and last for 5 days.
can i be pregnant? also or is this harmonal imbalance?
