My boyfriend and i had unprotected sex and we used the pull out method but he did not cum inside me just outside my vagina can i get pregnant??

Pregnancy: your chances are high. One of my colleagues on this site said it should be called the push in method. The problem with using this method is there are plenty of sperm in the pre-ejaculate or "precum" to fertilize the egg. Basically Penis+vagina+ovulation=pregnancy. If you don't wish to be pregnant use a better form of birth control.
