boyfriend just left my house. we had sex like 4 times today. the first time he pulled out and came on my vagina. he seemed kinda worried and i felt something weird but he didn’t say anything. i went to the bathroom after, and there was cum in my underwear.. we fucked a couple other times as well, and he didn’t cum in me again i don’t think.. except the other time he came on my stomach and he kinda touched it by accident i think and he touched the outside of my labia.. what are the chances of me being pregnant from today? (i am ovulating or in my fertile window or whatever)
