Aaah alam ko yan, mama, yung heaviness at pelvic pressure na parang may bumabagsak talaga, super common sa late pregnancy especially if you're on your feet a lot like you! A few of us moms from the barangay experienced the same thing, lalo na kung nagpapatrabaho or naglalakad ng matagal, kaya totally valid ang feeling mo. The belly and lower back pain plus na-stretch na ang lahat can definitely feel intense, but since you're almost full term na (35 weeks), mas important na talagang i-monitor mo ito, I'd really suggest you check in with your OB about it, kasi they'll want to make sure it's just Braxton Hicks or normal third-trimester stuff and not anything that needs attention. Especially with the walking to and from bukid every check-up, your body's working double time, so your doctor might have specific tips para ma-ease ang pain habang gumagalaw ka pa rin. Kaya mo yan, mama, you're doing great preparing for baby!
