Ay, mama, na-worry ka na, kaya please check with your doctor or OB agad, especially pag 36 weeks ka na! Heart rate can vary a lot during pregnancy, pero ito talaga dapat i-confirm ng medical professional para sa peace of mind mo. One of my mum friends had similar concerns, at ang OB niya agad lang nag-check, wala namang problema, pero super reassuring. Better safe than sorry, di ba? Hang in there, at update mo kami!
