Mama, please call your OB or go to the hospital right now para ma-check properly, 37 weeks and 4 days, any tummy pain with that feeling needs a doctor's eyes on you immediately, hindi kami pwedeng mag-decide dito.
A few of us moms had similar signs and iba-iba ang reasons, some were false labor, iba naman something else, kaya talaga kailangan ng check-up para ma-know ang eksaktong nangyayari. Don't wait, mama, better safe than sorry!
