Is it labor?

Im trying for a vbac this time and I do fully believe that baby comes when ready...so all the fun stuff to try really is just fun for me. I had the runs this morning but I had it my my whole second trimester sooo its like this morning im like hmmm is it a sign my body is prepping for labor? Was is that carmel brownie I ate lastnight?? Lmao These last few weeks are going to filled with lots of googling I feel like cause I have no idea what to expect. My first was breech and they took him exactly a week early so no idea hahaha
