Start of labor? Tmi.

April
I'm 39 week 1 day. Just randomly this morning I have cramps and the need to go poop, when I went my cramps got worse and it wasn't 100% diareah but wasn't solid. That was about an hour and 10 mins ago and I'm back on the toilet with the same problem. I'm not sure if it's just something I ate or an early sign of labor. I know your body wants to clean itself out before birth. Thanks in advance for any feedback!
