I'm 6wks pregnant and for about 4 days now I have had the WORST consistent nausea. Not only that but severe headaches. I've never felt so horrible I've lost my appetite due to the headaches and nausea. I don't know if it's just a headache or a migraine all I know is it's so bad I want to cry sometimes. My first pregnancy was never like this. Has any of you experienced this and if so what helped?
