A*S MUCUS 🤢😷

Hey! So recently I've been really constipated. I'm about 18 weeks and I figured thats semi normal and I'm dealing with it. But what I can't seem to find answers to is why large chunks of mucus leaks out of my a$$ and why there's a constant steady discharge? I have found (on the internet) a few pregnant women who have gone through it, but it seems mild compared to mine, and they dont have larger chunks. What is the deal?
