Yogi, as your hcg levels rise, it does slow down a lot. I'm sure your results are normal! But at the same time, I understand your concern. You might see a HB today. Plenty of women do. But, if you don't, it could just be too early. Also, if the rate is slow, it may be that the heart just started beating. This is why most Drs wait until after 7wks - before that, perfectly normal results can cause unnecessary worry. FX for great results. Please KUP.

ps. FWIW, I found I would worry terribly between each scan. We'd have a scan and I'd be worry-free for maybe 1-3 days and then I'd worry the entire time until the next one. I'd literally be holding my breath as each scan started. Even now, when I can feel her move between scans, I still find I hold my breath each scan until I see her move on the screen...
