Hi po everyone for sharing lang po.. normal lang po ba na hindi pa nakikita yung heartbeat ni baby

Hindi nakikita sa ultrasound po ba mommy? Sakin merong heartbeat 7weeks and then tinry ni OB nung 11weeks na if ma catch nya thru doppler pero hindi pa narinig at she says its Normal kasi nasa early pregnancy pa. The baby is tiny kaya ganun. Pero pag daw nasa 14weeks and up na wala pa din, something is not good na daw po.
