Mucus Poop

I am 39+5 and along with my normal pressure feeling down below when I've felt like I needed to poop or fart I have went to the toilet and it's like a watery fart (sorry for TMI) but it's not poop that comes out its like a mucus???

Anyone else had this?? I don't feel like I have an upset stomach or anything that I could put it down to.
