So far for my previous 2 scan at w8 n 12, I also no hear. But the person who does the scan show me at the screen, some flickering. They explain that the flickering I saw, is the heat beat. So I saw it, not hear it.
You can voice out to the gynae. Sometimes they don’t see the need to let you “hear” the heartbeat since you “saw” the heartbeat
You can ask. My gynae let me hear fetus heartbeat at week 9. When I did Oscar test sonographer also checked fetus heartbeat.
Oh u shd hear it at all your visits or maybe u ask your doctor for it. I heard mine at 8 and 12 both
