Sex sex sex .. Pregnancy

I'm not really looking for advice or answers just need to vent . But Pleaae feel free to comment !!! . So me and my boyfriend have unprotected sex a lot . We never use condoms , I'm not on birth control .. He does however use the pull out method which we all know is not a reliable source. Well last night I swore I felt him cum inside me and I felt extra wet .. Like I've never felt before . I just couldn't tell if it was from me or from him . We drove to the local cvs and they were all out of the plan b pill so today is his birthday and I didn't want to stress him anymore so I'm kinda like stuck not knowing ... Anyone ever have something similar happen or going on now ? We are engaged so it's not like a baby would be terrible it's just a lot to deal with on top of other things going on
