Uy, mama, please don't ignore this one, if the pain is really intense or you feel anything unusual, get off the bus and go to the nearest clinic or hospital, okay? Belly pain with back pain during pregnancy can be tricky, and you need a doctor to check properly. I know it's scary, lalo na FTM ka pa, pero safety muna. A few of us moms have been through pregnancy pains that turned out to need checking, better safe than sorry! Sit down, breathe, and if you can, message your OB or go to emergency. Tell them exactly what you're feeling like you told us. Praying it's just ligament pain or something minor, pero doctor lang ang makakasiguro. Take care, momsh!
