Uy, mama, at 37 weeks na kayo, please check in with your OB agad, okay? Even kung tolerable lang, better safe than sorry, lalo na with cramping na parang dysmenorrhea. Kailangan nila malaman kung normal lang ba yan or if it's something they need to monitor closely para sa baby ninyo. A few of us moms had similar experiences near the end and turned out okay lang, pero talaga, let your doctor decide, they need to check you properly. Sending you all the best, mama!
