Absent Cardiac Activity

Hello po. Tanong ko lang po sana kung may nakaexperience na dito ng no heartbeat sa first TVS and sinabihan ng ob na hintayin daw na lumabas kasi possible daw na huminto na sa pagdevelop yung embryo (possible miscarriage)? Nagpa 2nd opinion ako and sabi naman nung midwife na nakausap ko sobrang aga pa daw to detect ung heartbeat kaya inadvisan ako na magpaTVS ulit after 2 weeks. Anyone who also experienced this kind of scenario? Thanm you.#pleasehelp
