i had unprotected sex in feb and right away within 30 min took emergency contraceptive, levongenstral pill. about 5 days later i had a bleeding that lasted for 5 days, light bleeding. maybe from the ec pill. come march i had my period that lasted for 5 days then april around the same time for 5 days i had a period, with clots and all. now i am experiencing urge to pee all the time. can i be pregnant or the urination thing is separate?
