Had there been no complications though, I think I'd have taken comfort from a few things. First, seeing a hb. Always a great sign. If you see a hb of the normal rate and have no bleeding, it's looking pretty good! Second, speak up and demand scans if the anxiety is getting too much. Your mental health is important. Try to break everything into small milestones so you don't end up with a 40 week wait.
How are you feeling today?
