My 17 Year Old Daughter Has Vomited Several Times Today

My 17 year old daughter has vomited several times today right after trying to eat (fruit this morning, toast this afternoon). She kept down the toast but threw up right after taking ibuprofen for a headache. She also says she has trouble taking a deep breath but her chest doesn't hurt. No fever but she has chills. She has some cramping but that's likely from menstruation.
