Sickness with twins...

Has anyone found out they are having twins and feel only nauceous and have food aversions but nothing much else? I'm 9 weeks 2 days and before now i have had nausea all the time and havent wanted to eat much but no vomitting or anything crazy, since reaching nine weeks I feel almost normal again. I have my appetite back, I only feel nauseous once in a while and I have headaches here and there but other than that I feel pretty good. Just tired! Has this happened to anyone else with twins? I figured if you have twins you would be even more sick and for longer, although this is my first pregnancy so maybe I'm just lucky.
