28 weeks and experiencing looser bowels

Hi all.

So I’m finally 28w & a FTM. I have been experiencing a looser bowel lately every 2-3 days. I do drink lots of water & take vitamins, but I’m freaking myself out reading about diarrhea possibly indicating labor is near. I always thought constipation was the bowels during pregnancy.

I’d did have that in the beginning, however.

Has anyone experienced looser bowels vs constipation at the start of the 3rd trimester?

I appreciate all responses.

Thank you!
