Did I pee myself? or is it his cum

just to start off I know the difference between cum and pee but this is just something that has never happened before

So I just had sex and I was just like laying on my bed trying to catch my breath and I sneezed and a lot of fluid came out of my vagina, and my partner usually cums in me but it was really really liquidy and didn’t feel like cum. so then I coughed again just to see and more liquid came out and it did not feel or look like cum at all, so now i’m wonder if i peed myself, but i didn’t feel like i had to pee and it stoped and started when i “made” it(and i know i’m supposed to pee after sex but this was literally right after we finish lol)

and when I finally got out of bed andI saw my bedsheets and it was a huge puddle.

I just wanna know if anybody else has, i guess peed themselves after sex without knowing or feeling like they had to pee(and could control it) because I definitely didn’t feel like I was peeing. but could it also be that maybe his cum was just really watery for some reason??
