My friend was fertile the time when her boyfriend and she had unprotected sex and heis bf ejaculated on the top of her pubic thing (Near the vagina/withdrawal) and he think that there are some that left inside her. She have taken the first dosage of Nordette, September 18, 4:45pm, an hour after they did the deed. on then second dosage on September 19, 4:45am. Is there still a possibility that she will be pregnant? she is lack of sleep and stress everyday. And 1 week have passed still no withdrawal bleeding
