Sprintec side affects?

i have a weird headache. my back (all down my spine) is achey/itchy under the skin. my lungs hurt from breathing. my whole body just aches. i just don't feel good. how long until i should talk to my doctor? I just started sprintec, when should i tell her? cause i know you're supposed to give birth control 3 months. 
Edit: i checked my pulse and i had 30 beats in 15 seconds?
