Tired of feeling as if I’m starving!

Aria • Happy and tired

So I wake up every morning feeling full not wanting anything to eat. Two hours later I’m nauseous and starving! And feeling as if I haven’t eaten in days. It stays this way all day..... I’ve never had this happen with a pregnancy. I’ve had two boys. Now... All I want is food and my nausea pill... has any one else gone threw this?
