What's wrong with me ?

Yarely
After 5 days on birth control I got the worst Nasuea ever and didnt eat at all for 2 days straight .. I couldn't even take a sip of water or I'd feel worse .. I stopped taking them for a day or 2 maybe 3 don't remember and when I get hungry my stomach hurts and when I did eat this morning I couldn't finish half of my French toast ?!? That's not healthy can anyone tell me anything ? I feel hopeless
