Feeling blah

So that's how I feel about the magical wonderful thing happening inside me. I'm 7 weeks 5 days pregnant and feel constantly hungover sick exhausted and worn down. Don't get me wrong all of it is worth it and I would do it over and over again in order to receive the joy of motherhood. But is this what pregnancy is? Does it get better or should I just settle into vomiting and exhaustion and just hide out for 9 months? Haha
