Hi mama! Honestly, I'd suggest checking with your OB first before getting one, kasi may risks din kung hindi properly used, one of my mum friends bought a fetal doppler without consulting her doctor and ended up stressing herself out more when she couldn't find the heartbeat properly. Try Lazada or Shopee second-hand sections, or ask in your OB's clinic if they have recommendations, pero really best to do this under medical guidance para safe lang. Rooting for you!
