Nervous

Okay so I had sex for the first time on March 29 which was during a fertile window but not during ovulation. We used the pullout method and made sure that nothing of his got near mine. It’s a week before my projected period start date and I have mild cramps, limited discharge, and some nausea. I’ve been worrying about being pregnant for the last week and am curious if the chances of me being pregnant are high? Any comments would be greatly appreciated
