I got the depo shot 11/19/15 and had sex on 11/26/15 and didn't use a comdom. My boyfriend didn't ejaculate in me, could I be pregnant?

There is a possible chance, you will now, just have to wait and see. sorry, no way to know this soon

While the depo shot is reasonably fast acting, I don't think it is THAT fast acting. I would say to wait until you've missed a period but you will be missing your periods because of the shot. I would wait until christmas is, or after the new years, and take a home pregnancy test.

Depo is a great long term birth control. You should be safe. However, with that said, no birth control is always 100% effective. I've known women who got pregnant on Depo. If you are scared to be pregnant, and not ready to be a mother, it might be time for you to rethink having sex.

In addition to what was said... with roughly 28% of young people infected with HPV... (Which can cause cervical cancer) in addition to other numerous STD's. Sex without condoms is playing Russian Roulette.
