So I've got an at home baby Doppler and for the past couple weeks any time I use it, it's seems like I am hearing TWO fast heartbeats. And then I listen to mine to make sure I'm not crazy and mine is MUCH slower than the other two.. But at my 6 week ultrasound I only saw one little bitty bean.. Or at least. That's the picture they gave me. I have a family history of triplets and my fiancé has a history of twins.. I'm kinda freaking out. Could this mean they possibly didn't see bean number two? Or am I crazy and it's just one?
