Hypoglycemia?

I keep having these episodes where I feel like I’m going to almost pass out, shaking, clammy and even though I’ve eaten recently with in an hour or so I’m starving again so much so it hurts/ I feel like I’m going to puke. I have no other way to describe the feeling. I’m almost 8 weeks. Wondering if anyone else has experienced any of these symptoms. I know it’s not heart burn or morning sickness I had them both with my last pregnancy. The fact that I want to pass out if scaring me. I have a doctors appointment in a couple days but just wondering this too?
