Hi, I'm 22+4 and woke up this morning with a horrible stomach bug. Have not kept down any solid food all day, although water and herbal tea seem to be OK. I normally have an iron stomach, so this is new to me! What I'm wondering is a) when do I need to worry (ie. call doctor or midwife)? b) would it be helpful, and is it safe, to take an electrolyte solution (can't get to chemist so it would have to be home made)? TIA
