Thanks so much for all your replies! I'm still getting little waves of nausea but they are nothing compared to what I had. At least they seem managable now and frequent snacks actually seem to be helping.

I'm not too stressed (unsual for me!), just surprised at how quickly things can change. The little nausea waves I'm still getting are a nice reassurance though

Next scan is 13 March (yes, Friday 13th!!!) so not long until we see bubs again. Thanks for all your well wishes, stories and advice!
