Well my girlfreind said she bled a bit before she was supposed to start her period ( a day before) and its been four days now and she still hasnt started it. We had sex 5 times unprotected, i pulled out 4 times and jacked off (no precum inside of her) and one time i pulled out to slow and came inside of her a little bit. then we had sec 4 more times but this time was with a condom, and the condom didnt break at all. She is on the birth control patch, and she's supposed to take it off on friday (she did) so her period can come. But its been 4 days, she's a bit stressed out and tired from family and her brother (really annoys her). Like is said is it possible?
