Mucus plug?

I didn’t take any pictures because I didn’t realize till later it may be my mucus plug. So I’m almost 33 weeks and this morning I went to pee and when I wiped there was discharge with a tiny bit of brown in it. Like the length and size of a needle. I didn’t think much about it but as I kept wiping, tons of discharge starting coming out.

I’ve had discharge throughout the pregnancy but this was A LOT. Could this be my mucus plug or am I just overthinking this?

This is my first pregnancy so please be kind.
