I was given a sample Nuva Ring as well as a prescription for 11 months if I choose to continue it. My question is, if after I start using the ring and I notice some very unlivable side effects (which seems to frequently be the case with most prescriptions for me), would it be ill-advised to start taking my last prescribed packet of pills in place of the ring, or should I wait until my next period to start the pill again, and just use condoms until then?
