Hey ladies. I've been using my Doppler since about 10 weeks, and I've only found the heart beat once (I think) a few days ago at 11 weeks and some change. I'm now 12 weeks and I still can't find it. Should I be concerned or am I working myself up for nothing? I'm confused that I found it, now I'm further along and can't seem to find it. It also worries me because I see other women who have found it at 8 and 9 weeks. Thanks in advance for your help! ❤
