Has anyone else suffered gastro during pregnancy?

DH and I both caught gastro from Jacob. Both Jacob and DH are now over it (with the exception of diarrhoea on Jacob's part, but thankfully it doesn't seem to be upsetting him too much and he's not vomiting anymore), but I'm onto my fourth day of it now......

I was pretty good yesterday and was able to eat a couple of small things, but I'm back to vomiting/diarrhoea again.

I saw my OB on Wednesday who said the baby would be fine (had a scan too) but I've lost quite a bit of weight in only a few days and am really struggling with tiredness and the constant sickness.......
