Looks like my symptoms have returned for the morning at least 
feeling reassured. The DS has told the whole blooming school that mummy's got a baby in her tummy that's why she's fat (wasn't initially going to tell him incase anything goes wrong but I find being honest with children is key and he was concerned as to why I kept feeling so poorly) so at least I don't have to hide in the playground anymore 
have a good day ladies
