Aw mama, that sounds really uncomfortable na talaga, 33 weeks pa lang and the weight is already overwhelming, I feel for you! A few of us mums in my circle experienced polyhydramnios din, and honestly, what helped was just resting as much as possible (nakahiga talaga most of the time), wearing loose maternity clothes, and staying hydrated despite the fullness. Since your OB already cleared you, maybe ask her next visit about safe ways to manage the discomfort, like pelvic support belts or specific positions that ease the heaviness, kasi every pregnancy is different and she knows your case best. Hang in there, mama, you're almost at viability and relief usually comes once baby is out!
