pregnant and no appetite

up until I was 2 months , I wouldnt get hungry then when I first saw  my baby on an ultrasound I started eating more but now that im starting my 2nd trimester its getting bad again , I get full soo fast !! :( I thought they said by the 2nd trimester you get your appetite back but it seems like thats not the case with me , I get full with half a plate and then when I force myself to finish my plate I feel sick !! anyone else feel this way ? does it get better ?
