Am I pregnant?

I know that there is a little possibility that I am pregnant. I didnt have sex with my boyfriend but when he cummed on my stomach, I felt like there is a splash outside of my vagina. I also have my mens that day. I am now paranoid since this is the eight day of my mens, which is my first time, tho it's very little blood only.

Please enlighten me. I'm sorry, I think I just need validation, I'm afraid.
