Hello m 21 yrs old. Last month in my last day of period I had intercourse with my boyfriend with out safety n I took pills after 4 hours then after 10 days I got my period again in same month for 3 days after this I have urine infection and now this month I got my period not in normal days and now I can't hold my pee for a minute I need to rush for toilet and the when I pee it's just for a second only then it's done and when I pee I feel like it's burning. I want to know it's because of the ipills I took in last month or is it the sign of pregnancy . Please reply me soon .
