Uy mama, yan ay something na kailangan talaga ng doctor mo na i-check in person, please don't wait, go to your OB or hospital ngayon na if you're worried, lalo na at 37 weeks ka na!
A few of us mums experience tightening sa tyan towards the end, pero hindi lahat yun ay labor signs, kaya importante talaga makita ng expert mo kung anong nangyayari. Get checked ASAP para peace of mind mo at ng baby mo, better safe than sorry, 'di ba? You're so close na! Keep me posted, babe.
