Not eating?

I am 8wks today, and for the last 2-3weeks, I'm just not hungry. I'll eat just once a day usually at night because I know I need to. Anybody else just not feeling hungry? It's not that I'm nauseated or anything, just nothing seems appetizing. (I've had 3 miscarriages over the last year and a half, so this isn't my first pregnancy). And my numbers are up to 200,000 hcg.
