38 weeks, pooping different is it a sign?

Hi there, first time mom here and this is far to much information for a Saturday morning but here I go.

So before pregnancy I was always very regular for pooping and I’d say pretty normal poop.

Since being pregnant I’ve been sooooo constipated, like sitting on the toilet for an hour to do 3 tiny stones of poop, and that could also be days since having one.

Well I’m 38 weeks today, and the last two days I’ve had looser stools but not diahrea.

Now diahrea to me is running to the toilet and just about making it before you explode, so maybe this is my problem that I only see diahrea this one way 😂

Well I haven’t had that, I’m still having to strain and sit there ages but it’s much bigger sloppy-er poop. And more often, I went 3 times yesterday...... which can I just say was amazing I felt so relieved 😂

So My question is, is this type of poop a labour sign?

I haven’t lost plug yet, I’ve had heavy discharge throughout pregnancy so I can’t really say if it’s more.

Baby’s head is right down we were told Thursday at growth scan, they struggled to do head measurements.

And all I’ve really had is irregular mild cramping which I am guessing is BH or just general stretching.

Sorry for the long poop 💩 story 😂
