Doppler opinions

Selinaa

I had a miscarriage last year at 16weeks didn't find out until 19 weeks and I have a fear of this happening again Becuase they couldn't tell me a reason of why it happened just one of those things, I've been seriously considering buying a heartbeat Doppler and wondering has anyone tried it and liked it or tried it and it didn't work good and bad welcome I want the good bad and ugly lol. Thanks in advanced 🤔🙄 I'm 16 weeks now.
