Yesterday I had an awful upset stomach and took to my bed with a hot water bottle (not too hot to touch but still V. hot) I woke up 3 hours later having rolled onto the bottle with a really hot belly. I'm 13 weeks pregnant and my sister has told me this is really bad as you should avoid hot baths, hot water bottles as they can cause brain damage..
I'm now worried sick that I've hurt my baby.
Any advice
