Anyone have a gastro bug during pregnancy? How did you cope? Help!

El :) pregnant with my 2nd bump❤

My 8 month old picked up a gastro bug from another bubba and because i wss the one taking care of him of course a day later I'm passing everything yellow from both ends! (Sorry TMI!) Whenever i drink water it comes back up.

My son has vomiting and diarrhoea too but the OH is taking care of him whilst i try not to die upstairs.

I'm 29 weeks pregnant and dare i say it but I'd take the morning sickness back over this anyday.

Help! Is there anything i can take??
