There is a risk of becoming pregnant anytime that you are having unprotected sex. Even though he did not ejaculate after the condom was removed, if he released any fluid whatsoever ("precum"), it is possible for you to become pregnant. I wouldn't be too worried unless you have missed your period. If you do miss your period, wait about a week from when you were expecting it and buy a pregnancy test. If you're not pregnant, you may want to consider using a form of hormonal birth control so that you don't have to worry about this again. Remember that birth control does not protect you against STDs or HIV, so you may want to continue using condoms as well. If you don't want to (or can't) use birth control, just make sure that you have plently of condoms and if you're going to continue with intercourse after the male ejaculates, replace the condom with a new one. I wish you the best of luck!
