I am just over 9 weeks. After suffering 4 miscarriages & one chemical, I needed some reassurance. So I bought the sonoline doppler and already found the heartbeat. It took a lot of looking but I am sure what I heard was a beautiful beartbeat! Same spot as my u/s found it, and sounded just like every other doctor check up I had with my first baby! I am so thrilled! I wasn't expecting much but I can definitely say the best $40 I e ever spent!! 😍
