6 weeks pregnant and NO appetite at all?!?

It so incredibly hard for me to eat. I normally eat all the time, but ever since I became pregnant NOTHING tastes good. I have to basically force feed myself because it makes me sick having to eat something that I don't want to. Is this normal? I hate it and feel like I'm gonna hurt the baby because I'm not eating enough, but I don't think it's possible to eat anymore without throwing up. I can drink all the fluids I want, its just food that doesn't taste good. Any suggestions?
