I had unprotected sex frst on 16 but my bf masturbate in bathroom thn i do unprotected sex on 18 and he ejuculated outside but i can't take the risk so i take i pill on next day that is 19 march and after few minutes of i pill i again do unprotected sex and he ejuculate inside. On 21 march and i take i pill just after sex. My periods come on approx 23 date of every month but today is 25 and they don't happen. Now tell me what chances of pregnancy i have ?
