I feel so drained

Hey Mamas, I'm just about 7 weeks with my second and I feel absolutely horrible. I'm exhausted, I always have a headache and my nausea just turned into real vomiting last night. My first pregnancy was not at all like this, and on top of that of that I've got my little almost two year old tunning around getting into everything as toddlers do. anyone else getting hit hard with symptoms? 😷
