Hunger Pains?

Kira • TTC 1st for 15mons and I finally had my BFP!

So I keep waking up in the middle of the night with super hunger pains. I’ve never eaten in the middle of the night and eventually go back to sleep. But when I wake up in the morning I am starving and absolutely cannot skip breakfast without feeling super sick. But then, no matter what I eat I gag through it and don’t eat a full breakfast. 🤦🏻‍♀️What’s happening? Why am I so hungry during these hours?
