Is There A Chance Of Pregnancy Without Intercourse?

Hello... I have recently made out with my boyfriend, but as we did not have a condom, we never penetrated. However, because he was so focused, he ejaculated NEAR my vulva as we were doing things. I have showered afterwards to be careful, and as far as I could visibly see (and he looked as well for double checking) there wasn t any that ended up on my labia. I don t even know if you can get pregnant just from one or two or whatever amount of sperm getting on your labia, but I thought I should mention that I didn t seem to see anything, though the possibility is there. I know periods can be irregular, and as someone who can be severely depressed and stressed I know stress can affect cycles, but I believe it s been about two months total, nothing before and after making out. Only twice has there been any sign of blood, and it was a more thickly mucous slivers the size of my pinkie nail tip. I know one was before the make out, so there isn t a chance it was pregnancy that time, and I can t remember the timing of the other one. If there s any possibility, I ll go take a test anyways, but I want to know if you can tell me anything on the likeliness of the situation anyways, please, very much?
