Low Appetite since Trimester 3.

Hi Mummies. I am in Week 30. My appetite has bad since i got into 3rd trimester. No cravings, just sudden loss of interest towards food and eating. Nothing seems to hit my taste even my comfort food in earlier trimester or pre-preg. I will constantly feel hungry and dizzy but the thought of food, makes me nausea. Any advice how to boost up the appetite?
