Cramping and Frequent Bowel Movements 33 Weeks

For the last 2 days I’ve been experiencing mild cramping in my lower abdomen/stomach/uterus area that sort of feel like what I get before my period. This is followed by the frequent need to poop (sorry for the TMI). It almost feels like my body is trying to clear everything out. I’ve heard that can be a sign of approaching labor. Has anyone experienced this? Not sure if I should be concerned or if it’s just a stomach issue.
