I just have a question... why did you douche? Did you know that can increase your chances of getting pregnant? You would think that it cleans out your system to get rid of sperm, but actually it pushes sperm and helps them along the way making it more likely that you will get pregnant.
"The liquid in the douche can force the semen and sperm further into a girl's body, shortening the distance between the sperm and the egg, increasing the chance of pregnancy (http://www.sexetc.org/faq/pregnancy/925). "
It sounds like with the timing you had sex in the last few days of your period which also increases your chances because you are closer to ovulation than at the beginning and since sperm can live for a few days, it is not only possible, but it has happened many time.
Since you have been on the pill, taking it everyday and hopefully at the same time everyday (which in my experience, doctors don't tell you!) then hopefully you are fine. Just don't make the mistake of thinking just because you are on your period you can't get pregnant. And don't douche! It increases chances of getting pregnant and it's bad for your ph balance and can lead to infections.
Good luck!
