Extreme hunger all the time at 7 weeks—normal ???

First pregnancy, so I’m pretty clueless😂 I’ve never been a super hungry person before, just normal meals and not eating a ton because I haven’t ever really needed to. Starting at about five weeks and more and more frequently (7+6 right now), I get these really intense waves of hunger where I get super shaky, breathing gets faster, and I’m just desperately hungry😂 I haven’t announced my pregnancy yet and don’t have my first appointment for a few weeks, so I don’t have anyone else to ask! Are we all hungry girls this early??? A little worried about gestational diabetes but I don’t even know if you can get that this early🤦🏻‍♀️
