Mama, please see your OB agad, abdominal pain with that feeling, especially at 8 months, really needs to be checked right away para sigurado na okay kayo both. Hindi kami dapat mag-assume kung normal yan o hindi, kaya please don't wait on this one, ha? A few of my mum friends had similar concerns mid-to-late pregnancy, pero lagi silang kinonsulta ng doctor para ma-rule out anything serious. Tyan tightening ay common, pero combined with what you're describing, better safe talaga. Let me know how you get on, praying it's nothing, but please go get checked, okay?
