Can no longer pick heartbeat up on doppler

Jade

I’m 11 weeks and 5 days and for the last 2 weeks been able to pick up a heartbeat (longest time 20-30 mins).

I managed to pick one up this morning but I tried again this evening and couldn’t find nothing after an hour of searching.

I’m so worried that the baby has died as I normally can hear something, even if it’s faint/ comes and goes but now nothing.
