unprotected sex.................with no birth control

I had unprotected sex on a day i was ovulating, but he didn't ejaculate inside of me he pulled out, could i be pregnant?

Yes, its possible you can get pregnant this way, Pre-ejaculate, (aka precum, the clear fluid that leaks from the penis when aroused) can carry small amounts of sperm in it, and men cannot feel it escaping.

Many women get pregnant from using this "withdrawal" method each year, it has a high faliure rate and is not a medical, reliable form of birth control.
