9 weeks! Experiencing no symptoms except always cold and SUPER hungry!

Nikki
To our excitement I'm 9 weeks into my second pregnancy! I was so worried something was wrong because despite my dozens of positive tests I feel completely normal! With my first I was so nauseous and tired; I barely ate anything, had TONS of food and smell aversions and constantly wanted to take a nap. This time around I have a ton of energy and I am CONSTANTLY hungry. No morning sickness, no nausea, nothing at all!  All this had me panicking that something was wrong with the baby because feeling this normal doesn't happen, right??! Anyways...the ultrasound, to my surprise, showed a thriving baby with a strong heartbeat. I'm thrilled but also having a hard time believing this is real! Anyone else experience this or had vastly different pregnancies like I am??
