Good morning, nak! Yan kailangan i-check mo talaga sa doctor, lalo na kung bago lang yan para sayo, numbness or that creeping cold feeling in the lower back ay mas safe na consultation muna bago mag-assume. A few of us moms experienced similar things during pregnancy or postpartum, at ang bawat katawan talaga ay different, kaya better safe than sorry! Especially if it's paired with other changes, kahit walang sakit. Sched ka na sa OB or regular doc para ma-rule out anything, okay? Take care, and don't worry, most likely normal lang yan, pero importante check lang.
