Hello.. On the 17th of April,my period started..then on the 20th I had unprotected sex(he didn t ejaculate) but I took some contraceptives.. Then my period came on the 12th of May(it was light though,I normally have heavy periods)so I guess it was because of the contraceptives..had unprotected sex on the 15th of May and took postinor2. Light bleeding started on 20th May..till today 22,even had to wear Pad.. I don t know what s wrong,Please help me. Is it a sign of pregnancy?I hope not,and ths light bleeding,is it my period? Because my period is supposed to be due on the 5th of june. Please explain.thank you very much.
