Birth Control

So we lived near a walmart and I had my doctor send my prescription for birth control there but we ended up moving but there is a different walmart here how would I go about changing the place I get it at? I really don't want to call to ask because honestly it makes me feel a little dumb and embarrassed lol are all the pharmacies connected where I could just call in a refill at the closer walmart or would I have to go to the old and ask for them to send it to the new one? The old one is quite a ways from where we are now so I didn't want to drive there for no reason
