Leila - the fatigue is really normal. And it's different to "normal" tiredness you get. I'm one of these "just push trough it types" but in my first trimester that was impossible - my brain said one thing but my body was headed for the bedroom! There are a lot of changes happening right now like increase in blood volume, increase in metabolic rate and all the major organs of the baby are forming. No to mention the progesterone which also make you feel tired. Give in to your body, do what it tells you, rest when you need to. You get your energy back in the second trimester (or by 20 weeks at the latest!)

Sorry to hear about the m/s
