pregnant??

How high are my chances of being pregnant if First time I had unprotected sex couple days after my period ended but 4-times within a month & two of those times were during ovulation. The last time was during 33% chance as eve said. I'm not quiet sure how Precum works around it but either way he said I was good all 4 times. I'm not 100% sure if he Cum in me or not, But I felt cum-like around on the outside when he'd pull out because he would finish outside close to my v. & lately I've been having cramps and fatigue etc. & also he's been asking more about what would occur if I was to come out pregnant.
