all day sickness help

I need help! I was originally told that I was 10 1/2 weeks pregnant, however at my appointment on Monday it was confirmed I'm only 7 1/2 weeks pregnant. I have been dealing with all day sickness every single day for over a month now. I've tried everything. Eat more fruit, drink more water, Prego Pops, honey straws, etc. I'm in bed all day, everyday. I can't eat without either feeling awful all day or throwing up. Please help! I'll take any and all suggestions.
