Mamsh, 37 weeks ka na kaya normal na talaga yung Braxton Hicks contractions mo (yung hardening ng tiyan every 10-30 mins), lalo na kung di consistent at nakakalampas ka pa rin ng 30 mins, pero since you're already 1cm dilated and the pain is starting to bother your daily walks, I'd really suggest mag-message sa OB mo even if next appointment mo pa Dec 1, better safe than sorry especially when labor pain starts mixing in, kaya don't wait na! Stretch your hips, stay hydrated, and take warm baths kung kaya mo (a few of us swear by that to ease the achiness), pero seriously mamsh, check with your doc about what you're feeling, she'll know best kung labor signs na ba yan or if you need to come in earlier.
