Mucas? Discharge? HELP!

I’ve been having to wear panty liners because I have frequent leakage. It’s never alllot but something there .. this morning i went to the bathroom, and after, all of this came out at once. It looks kinda thick in the picture but it was very liquid-y.

This isn’t my mucus plug or anything is it? After that I haven’t had anything else come out. No pain or anything. And I could feel him moving around afterwards.

This is my first pregnancy and don’t have many people - family or friend - wise to ask.

TIA
