BC Side Effects

I’ve recently started taking the pill & been on for about 4 days.

Background Info: I’m 17 & weigh 100 pounds. I’ve always been a person that naturally doesn’t eat much. I mostly eat small portions & junk food & don’t gain weight.

Some effects i’ve been experiencing from the pill are nausea & fatigue. Sometimes when i’ve haven’t eaten all day & smell food i still end up feeling nauseous. What do i do? 😩 I don’t have any sense of appetite but feel like i’m just starving myself.
