OK so clomid wasnt the best thing to do....but its not the end of the world. Either a large dose of birth control pills. OR BETTER yet a RU486 dose would probably help at this time. Giving her clomid does induse one ovulation but NOT instantly. I dont think that if your semen was in her last night and you gave her clomid in the morning that it would be possible. I could be wrong. Just stay on the safe side and take her to a clininc for a "morning after pill" and try not to stress TOO badly about it.
