Mommy, please see your OB as soon as you can, especially kung ang sakit ay biglang lumaki or may other symptoms like bleeding or fever, go to emergency right away, okay? Alam namin lahat ng iba't ibang aches and pains sa pregnancy, pero it's really important na ma-check ng doctor ang back pain at leg heaviness mo para ma-rule out kung may issues na kailangan ng attention. A few of us went through different pains during pregnancy, pero ang bawat kaso ay unique kaya better safe than sorry talaga. Huwag mag-alala, maraming moms ang nakaranas ng ganito, pero you deserve proper checking para ma-assure kayo both safe. Let your doctor guide you, ha?
