Poop 💩

Seeking some normalizing. Just passed 26 weeks, and about once a week now throughout second trimester, I have a full day where I poop so much, it’s inconvenient and annoying. I’m not constipated throughout the week in any way. Totally regular. Just have this one day a week where it’s like my bowels are cleansing every single thing for about 5 hours. It comes with a little bit of nausea, where my mouth waters. Anyone else?
