Loss of appetite, dizzy

Amber

31 weeks tomorrow. Ive noticed that my appetite has diminished, A LOT. I ate a bagel around 830am and a few bites of steak and a couple spoonfuls of mashed potatoes around 2pm. It's 9pm where I live and I'm ok. I used to eat allllllll day. I'm hungry but if I don't eat tonight, I would be fine. This is strange. Probably going on day 5 of feeling like this. And I'm feeling light headed, woosy, like my equilibrium is off. This has been happening for a few weeks now, the dizziness. Anyone else ? I drink fluids all day long btw.
