Pregnancy symptoms

Is it normal to be short of breath in early 2 months/ 8 weeks of pregnancy. I started feeling like this, maybe around 6 weeks. If I don’t have a good meal, I feel terrible and sometimes I don’t even have energy to make food. Almost most of the time I’m loss of appetite. I’ve been staying hydrated, drinking about more then one bottle of water a day. 3/4 at most. And taking my prenatal vitamins daily.
