Pros/Cons Home Fetal Doppler

Hi ladies,

Curious to hear both sides, here - I plan to speak to my OBGYN about this next week, because I’m absolutely frantic waiting for the anatomy scan (currently 15.5 weeks). If you use the doppler, how often do you use it, and for what length of time? Did you speak with your doctor about it? Any particular types? Do they all have the potential to overheat tissue? Anyone hear from their doctors that it was not advised (aside from potentially not finding the heartbeat and scaring yourself)?

Any and all points of view welcome!
