Hi Doc, We Had Sex With My Husband Last Night

Hi doc, we had sex with my husband last night (I really don't remember the exact time tho, but its merely 2 or 3 am), and unexpectedly he ejeculate in my body which is very dangerous because I really dont follow up my menstrual cycle. I'm extremely worried because I really dont want to get pregnant. what I did is I search for alternatives and I found out about emergency contraception pills (specifically nordette) and I told my husband to buy me one. he founds out that nordette is phased out . and so the pharmacist gave him marvelon 28, which is not an emergency contraceptive pill. so what I did is I take 1 pill first (9:52am) and found out in your page (last post) that it needs 4 pills to take so after 3-4 minutes (after reading the post) I take another 3, how accurate is the possibility I will/wont get pregnant ? what should I do to prevent pregnancy? plss I really need help doc. hope you',ll consider. were currently staying in Philippines.
