Being taken advantage of?

I’m a medical assistant in a primary care medical office. I’ve worked there for over a year and currently (to my best knowledge) make less than most employees. My experience is limited to two years with a previous company and I am on the younger side.

Out of all the employees I work the hardest and take on extra side projects/overtime the most. Today was kind of a breaking point (similar situations happened 4-5 times). We are usually staffed to have 6-8 people for around 10 patients or so. Today we had 4 people for 20 patients. I was completely overworked and the doctor was aware of that and was trying to make some light jokes to ease my mood. I have been working there a bit over a year and no raise or any other kind of compensation.

Am I severely being taken advantage of? I would hate to leave a job only after one year, but I would like to increase my income and not have the problems of being short staffed (which happens at least once a week). What should I do?
