Is there any tips on how to reduce the nausea and vomiting..? I'm vomiting almost everyday and yst was the worse, I vomit so hard till I have tiny petechial lesions on my face due to straining from the vomit and I can't seem to control it.. but I know I need to eat for the baby so I've been having small meals every few hours but it's so hard.. please help. #1stimemom #pleasehelp #advicepls #firstbaby
