Aww mama, ganyan talaga ang feeling kapag ganitong advance na ang pregnancy, ang pelvic pain at numbness ay super common sa final weeks kaya hindi ka nag-iisa, a few of us din experienced yan at ang hirap talaga matulog at maglakad! But since you're having significant pain at numbness, it's best to check with your OB para sigurado lang na walang nerve compression or other issues na kailangan i-address bago mag-labor, especially kaya na lang sabi mo 36 weeks na, better safe than sorry this close to delivery. Try sleeping on your side with a pillow between your knees, at mag-rest muna sa heavy walking if you can, pero definitely have your doctor check you out, okay?
