39+5 & crampy

It started around dinner time last night I felt a lil crampy by the time I went to bed they were starting to feel more like heavy period cramps. I was up all night peeing and still felt a little crampy. I'm up now for work and I'm gassy and have heavier cramps. My lower back is always sore too so I blame it a lot on that. No blood or contractions. Praying this is a way of my body telling me labor is near!
