<s>[INST] Hi, me and my gf had sex yesterday and finished around 1pm. Accidentally when I pulled out, the condom was stuck inside her vagina as in literally inside. After 10seconds of realizing it was stuck inside I pulled it off, I am not really that sure if there was a leakage or if I ejaculated in the condom or inside her. At 2:28pm the same day she took Nordette (4pills at once) and at the next day 2:28am (after 12hrs) she took another 4 pills. Is nordette really effective? What are her chances getting pregnant? Thank you [/INST] Hello dearI understand your concernDo not worryChance of pregnancy is less.Nordette sed in correct dose and it is highly effective in preventing pregnancy.It isupto 80% effective in preventing pregnancy.It may cause delayed in petiod by1-2 weeks.If nex period will delay by more than  2 weeks then consult gynecologist.Avoid stress, take healthy diey, drink plenty of fluid and do regular exerciseBest regardsDr. Sagar </s>
