Stomach ache and loose poos

Are those very early signs of labor? I’m 35+5, haven’t had cervix checked yet so not sure how that’s going..but for 3 days I’ve had an upset stomach - cramps and just feels bad - and very loose some times diarrhea poo. Ive also pooped like 5 times a day! Not usual..I’ve heard this is the starting signs of labor? Was it for you? Otherwise I’m thinking I might have eaten something bad.
