Third trimester so tired, but not hungry?

Helena

I’m 30 weeks and 2 days and I’ve been just sooo tired in the day time like I wake up around 2 pm but it’s understandable since I don’t sleep till late because it’s been hard to fall asleep at night since my baby is so active it keeps me up and restless leg and hot flashes. But the only thing that worries me is my appetite has decreased by a lot, and that worries me because I know this is when my baby should be packing in her pounds. But I feel like I have to force myself to eat and I’m so tired I’ll sleep in and force myself to wake up to eat, I’m trying to eat small meals ever 2-3 hours but I’m starting to feel nauseous doing it. Does or did this happen to anyone else? And what was the solution???
