Aww mamsh, ang laking bigat talaga nun! Para sa inumin, stay hydrated lang with water or coconut water para may energy ka during labor, maraming moms swear sa coconut water kasi naturally may salts siya. Pero honestly, best alam ko lang is to talk to your OB about what's safe to drink during active labor kasi may mga doctors na may specific guidelines, lalo na kung may IV ka na or epidural, so better sure tayo together with your doctor on this one, alam mo?
For the heaviness and low tummy, yan talaga ang gastos ng last stretch! Try pelvic tilts, walking kung kaya mo pa, warm compress, at rest with feet up when you can, ilang moms din namin nag-try ng maternity belt para ma-ease off ang pressure, medyo nakatulong sa kanila. 38 weeks at 2cm pa lang, kaya mo pa yan! When's your next check-up with your OB? Mention the heaviness sa kanya so she can check if lahat normal lang.
