Uy, mama, yan na rin ang naranasan ko at ng ilang mum friends ko towards the end ng pregnancy, ang tiyan talaga ay nag-harden at nag-soften, plus back pain and weird tummy sensations. But dahil may pain ka at uncertain ka kung normal lang, please don't wait for bukas, go to your OB clinic or emergency room today para ma-check kaagad, lalo na at 37 weeks + 5 days ka na. Better to be safe, especially with the back pain at tiyan hardness combo. Wag mag-atubili, okay? Your doctor needs to examine you properly para masiguro na lahat ay okay sa inyo. Sending you both love and praying it's just Braxton Hicks!
