My morning sickness seems to have gone severe all of a sudden but what's worrying me is I am feeling extremely faint dizzy and shaky after it. Is this normal or is this a cause for concern? Not felt this bad will all the MS I've had. I have my antenatal appointment next week but do I wait until then or do I phone triage? Could I be dehydrated? I'm trying to drink loads. Appreciate any advice/help.
