I have a doppler. I bought it when I was around 11 weeks with this bub. I found a hb for the first time at 11 wks 6 days. I currently use it around twice a week for less than a minute each time. For me the doppler has offered peace of mind but I can see how it would offer anxiety often too. I use it simply because I just love hearing that little hb when I need to. This pg I have anterior placenta so movements are not as soon as as strong as DS so I will probably stop using it as often once I get more regular movements. Big Hugs - I can relate slightly to the way you are feeling, I had two m/c prior to DS and then I had some early and late bleeding with his pg. He was a clomid bub too.
