Mama, ang belly pain after IE is totally normal, yan yung cervix trying to soften, so walang rush with the walking and squats kung di ka ready! A few of us had the same thing and honestly, what helped more was just resting and letting the Evening Primrose do its job, kasi puwede ring mag-trigger ng contractions if your body isn't ready yet. Since you're already 36+ weeks and the lying-in cleared you, light walking is okay if gusto mo, but listen to your body talaga, if you're uncomfortable, just chill and let labor come naturally. Definitely check with your OB or the lying-in staff kung ang pananakit persists or gets worse, kasi they know your situation best! Wishing you a smooth delivery, mama, you've got this!
