Second Baby!

Karuuh
Hey ladies. 
So this is my second time going through this wonderful experience, and the first time, I didn't experience any pregnancy symptoms. 
I'm on day 3 missed period but I've been feeling highly nauseous unless I eat something quickly, I'm tired all day, I get light headed, and my stomach feels super bloated. 
It's too early to test, but has anyone else experienced symptoms on their second and not on their first?
