Switching to new BC ?

I've been on my birth control, Lo-estrin 24, for about 5 months now and it's just not working out for me. It's not helping with my cramps anymore, it's not helping with my acne, and it's made me very emotional. I had the same symptoms occur around the same time frame with my previous birth control, Yaz, and that's why I switched in the first place.

I want to switch my birth control to something new, but here's my dilemma. I originally live in New Jersey which is where my gynecologist is located who prescribed me my birth control. I now go to college in Florida. My question is could I go to my campus' health center and ask them to prescribe me a new birth control (they do prescribe birth control to students) even though my current prescription is from my gyno? If not, can I just call my gyno and have her make the switch or would I actually need to to make an appointment? My next appointment with her isn't until June and she's packed until then so I will have to wait until then if this is the case.
