Hi!
I would definitely recommend doing a test. Douching is not a very effective birth control because those darn swimmers (sperm) can get where they're going within 3 seconds!
Douching will help to wash out some of the residual, but the ones you need to worry about are already long gone!
Do a test, then get in to your doctor for some better birth control!
By the way, have you heard of Plan B? That is a prescription that you can get from Planned Parenthood or your local emergency room for exactly the situation you just described. Its very easy--only 4 pills--and no baby! Its also called the morning after pill.
You can take it up to 72 hours after the fact.
Good luck!
Dr B
Okay I had sex again but the day after my ovulation day and have not done anything about it. Is there a possiblity that I could be pregnant? But I am also having some cramps today. When I had sex was on Friday and today is now Monday.
