Low appetite at 17weeks pregnancy

Hi mummies! I dont have much appetite still. At this stage I'm supposed to be eating well already,but unfortunately I'm still not picking up on the appetite. But according to gynae checkups baby is growing well. I can only take spoonfuls of rice and depends on dishes what dishes i can take in. Seems like most of it is to my dislike and its quite hard to find something interesting to eat at the moment. Any Mummies here experiencing same situation? What to do? Should i be very worried since I'm not eating much.
