If you haven't already, you need to buy one!! I'm 10+5 weeks today and I hasn't had a scan since 6 weeks 5 days and I always had a fear of something happening or going wrong with our baby. So I finally gave in and bought the Sonoline B from baby doppler.com and it was the best purchase I ever made. After 5 mins of searching and 4 weeks of worry that our baby would just disappear, I found the heartbeat! Strong and healthy sounding just like at 6+5 weeks! I am so so happy! I could listen to this all day<3
