Last time I got periods on 8 feb 2016 and this time I got periods in 11 march 2016. And Always I got periods by irregularity. On the third day of my period on 13 march I have intercourse with my partner and I think we did a mistake and we did not use any precaution. And I got little bleeding on the 3rd day And I go toilet after the intercourse. So is there any chances of pregnancy or not? And actually I do nt want pregnant in this time so please give me suggestion what should I do now? If I wants to take a pregnancy test them after how many days should I take it for confirmation? Last tym about a year ago I have taken UNWANTED 72 and I got weakness so much. So would you please tell me if I take this then how can I avoid weakness by using something please tell me?
