I just got off my period last week and as soon as i got off my period i had unprotected sex and now i have been cramping but he pulled out?

Unprotected sex: At any time always has the chance of becoming a pregnancy, and/or one of many various std's: hpv (which can cause cervical cancer), herpes, gonorrhea, chlamydia, crab lice, trichomoniasis, etc. Using a hormonal birth control is generally a good way to protect against an 18 yr ball and chain-but condoms are really the way to protect from the others. Check preg test with first morning urine is best.
