Am I crazy?

Lee

I had gestational diabetes my first two pregnancies. I was diagnosed around 28 weeks my first and the second I was diagnosed later around 32/33 weeks after passing the one hour but showing signs and tested the 3 hour. My husband and I are currently TTC and I’m only 4 dpo but I’m having GD symptoms. My first sign for both pregnancies was shaking when I was the slightest bit hungry and that’s been happening yesterday and today. Could I be pregnant? I don’t usually get like this so I don’t know what else it could be?! Has this happened to anyone else and they were pregnant and knew this early?
