I had sex with my "guy" on november 17, the day after my period went off. We didnt use a condom but i did not come( or at least i think i didnt) and he only pre came. How soon can i find out im pregnant?

you would have to wait about 2-4 weeks. Pre-cum CAN make you pregnant! good luck.

The best way to find out if your pregnant is wait till your next period and if you get it but it doesn't seem normal take a test, and if you don't get it take a test. Good luck, hope all goes well for you.
