I'm not surprised you didn;t hear from the clinic yet, as you said they were very busy, and rushed. Send her a thank-you note, and ask for a follow-up, perhaps. And I do think it's a good idea to call the nearby place Monday on your lunch. A resume is a piece of paper and can get lost in the shuffle, either literally or figuratively, but a phone call and a pleasant person on the other end is easier to remember. Be positive, and upbeat when you call in, you needn't mention this is the third time you've sent a resumé in, just "Hi, This is Jessika Xyz, I wanted to be sure you got the resumé I recently sent in, as I would love to work there! Who would I speak to about this?"
