6 weeks and 2 days pregnant.

For the past few days I've been struggling so bad with constant everyday, all day nausea. It's making it hard to eat and sleep. If I smell strong foods it makes me retch. My stomach cramps up from being so empty and so all over the place. When i do manage to eat a meal later on it feels like im gonna throw it back up. I have yet to be sick, only heaves and retches.

Does anyone have any ideas to help? I've got a scan tomorrow so will be mentioning to the midwives at the hospital but for today can someone please help?
