Blighted ovum or not

#advicepls I need to enlighten myself, today nag pa check up ako and ultrasound on our nearest clinic here in province. The result has gestational sac but no fetus seen on the ultrasound result which is dapat meron dahil yung last LMP ko po is october 26,2023. I have a second ultrasound which is showing na may fetus and heartbeat possible po ba na nag miscarry ako?
