just started on the pill

I just started taking Mono-Linyah two days ago, and the only side effect I've experienced is a upset stomach and fatigue. I'll wake up and still be tired, and I'll be hungry but as soon as I start to eat I'll feel nauseous. The nausea isn't that bad, I just have the feeling that I might throw up but I don't. Is a normal for someone who just started taking bc for the first time?
