new grad first job in urgent care office...good place to start my career???

I am a new grad and having trouble finding a job. I have the possibility of taking a job in an urgent care doctor's office. One of those "doc-in-the-box" type places. I need the income and want the experience, but will it make it harder for me to get into the hospital? My ultimate goal is L&D, but I am willing to put my time in to get there. Is it ok to not wait it out for a hospital job as my first job? I do not want to get stuck working only in doctors offices my entire career.
