I've had some toast with honey on it this morning, can't remember what you are supposed to eat or not eat when you have gastro. My brain is totally fried and my house is a mess and I'm on my own today because DH starts his new job at the hospital!
You can eat whatever you feel like. It's just usually people prefer bland food coz its not so bad coming back up. And I'd recommend you steer clear of food that'll upset your gall bladder especially, as you don't want issues with that on top of the gastro. I really hope you're feeling better soon. I hate gastro, and to have it at 38.5w pg is no fun, especially with 4 kids to look after. Lots of hugs.
