My Doppler picks up all kinds of crazy beat counts. But I know it's pretty accurate when I can count the beat right along with it. Sometimes its 220 something (baby behind the placenta) and sometimes it 60 something (just blood flow or my heartbeat). I try not to worry too much until I know I have found the baby and am getting a steady beat (which is hard, mine likes to run from me). But its hard. I am a ball of worry at this stage and always have been. I just need to get beyond the anatomy scan and then I might be okay. For a first milestone at least.
I do try to limit Doppler and sonograms for paranoid reasons. With DS 1 I had five sonograms. With DS 2 I had double that (10). This time I have had five so far and expecting at least 2-3 more. But I try to only use the Doppler once a week and that makes me a little less paranoid. I do feel baby pretty regularly lately. Although I did listen last night, just to check. Baby seems to be sticking to 160, but she jumps around ALOT for my liking. I have gotten readings from 140-170, both at the doc and at home.
I do agree that waiting is the worst part of the sonogram thing. It nearly killed me those last couple days. And I am already doing it for my anatomy scan, wanting to know all is okay and healthy. But I generally am a nervous person, so I imagine that plays into things a bit. I obsess about things, so it makes sense that if I have something to be concerned about...I'll be obsessed. Sigh. I will be going back on my meds at 20 weeks. I hate to use them in the beginning when all is developing though, just in case.
