Doppler

I tried a home doppler yesterday for a literal minute and couldn’t find a heartbeat; hung it up immediately. (17+6). Too anxious to try again and overall beginning to become depressed as the thoughts come creeping back in. My OB was able to find it about 1.5 weeks ago in about 30 seconds. I know they say err with caution for this very reason but I can’t shake the anxiety. :/
