5wks pregnant&i have no appetite.i eat a little just to have something on my stomach. i am not sick nor nausea.is it normal or should i see a doctor?

Probably normal.: During the first trimester (the first 12 weeks of your pregnancy), it is not uncommon to have nausea, vomiting or anorexia (loss of appetite). However, recent studies have shown that eating too much or too little during your pregnancy will increase your child's chances of developing obesity. So, try to eat a healthy meal at least 3 times a day.
