I started the birth control pill yesterday. please read?

I am 16 and started the tri-cyclen lo birth control pill last night. I am using it for acne. I did not take it with food, i took it at 10:15 at night. I woke up this morning and my stomach was hurting, it felt like i was going to throw up all day and i felt really full. If i was standing/walking around i felt better but if i sat the pain would come back and i would feel like i would throw up. I ate a homemade muffin and water for breakfast, i could barley eat it all. I did not eat lunch. I am afraid to throw up. not long ago i ate some noodles (sidekicks) for supper. I have been drinking ginger-ale all day (one can) nad still don't feel good. I don't know if it is from the medicine. If it is how long will it last? tips on getting rid of the effects? Will the side effects go away? Will they come back every month when starting a new pill pack? did you get effects (if you were on a birth control pill)? should i have it with food? anything else you can tel me? thanks.
