Mucus Plug?

So I woke up a few times to use the bathroom overnight but I didn't turn the light on or look in the toilet or at my tissue or underwear as I usually do. This morning when I got up to get my 5 year old ready for school & I had to use the bathroom again. So this time I turned the light on & I noticed there's like bloody tissue (kind of like bloody show) in my panty liner. I'm 32.4 & I've been having cramps all night so I'm not sure if I may have passed my mucus plug without noticing overnight or what.
