Hey Anon, Don't worry. First three- four months are like this. Gradually you'll gain your appetite. Make sure that you take meals on time and stay hydrated.

it happens ... its somewhat normal for some .... as pregnancy grows week by week ..u will start gaining weight... but for now try to have  small small meals... u can have dry fruits, juices, salad...

It happens to some expecting moms. Even I lost my appetite. But don't worry your baby is still growing. Keep taking liquids, fruits and salads.
