Fertility Clinic called me

I had left a message on Monday that my cycle had started but they were not able to get back to me that day so I recieved a call today from Melanie (Nurse at Fertility Clinic) she said that I need to start my first birth control pill Wednesday night this is 2 days before I should have started my new pack of birth control pills. She also asked me if the birth control I was on was consistantly giving the same amount of the dose each day that month. I called my pharmacy and asked them and they said that Tri-nessa changes the dose each week. So I called Melanie back so that she can call me in a new perscription for a pill that will be the dose she wants. So I need to pick that up on my way home today.
