33+6 - think I lost a bit of my mucus plug!

So I had a bad stomach last night (sorry tmi) and after I'd finished on the toilet I wiped and noticed a thick gooey sort of discharge. It was about 5cm long and 1cm thick. It didn't have blood in it so I'm not sure if it was my entire mucus plug or whether it was just some of it. Slightly paranoid it's a bit too early. Have any other ladies had theirs comes away or bits come away? Hoping it doesn't mean labor is going to start soon!
