My gf and I had intercourse last June 7 (7 days after the last day of her period). I ejaculated inside her but I had a condom on so I figured it was ok but we later found that the condom was broken. She took 4 Nordette pills approx. 30 mins to an hour after we did it and another 4 pills 12 hours after that. She was nauseous and had headache for a day but no other side effects. However on June 12 she had some sort of discharge that has been present for a couple days but is gone now. What could it be? Please help.
