Side effects of the pill?

re

Hello, so I'm 17 and I just started taking my birth control and everytime I eat I feel so nauseus, sometimes I feel like im going to throw up and then my belly starts ti get full of gas and its really uncomfortable and i dont know what it could be causing that. I've red the side effects of my pill and nausea appears on the "less frequent side effects".

Does anybody else get this sinctoms or is it just me??
