Mama, yan ay medyo concerning talaga, please go to your OB or to the hospital right away para ma-check agad, especially at 37 weeks ka na. Hindi dapat mag-self-diagnose tayo dito, kailangan ng proper ultrasound at monitoring para alam natin kung ano talaga ang nangyari with baby's heart.
A few of my mum friends din nag-experience ng ganyan, at lahat nila agad napunta sa hospital, importante lang talaga na ma-rule out any concerns ng doctor. Wag mag-worry masyado, marami ring positive outcomes, pero kailangan mo ng medical check kaagad. Praying for you and your baby, mama!
