How many times can you receive a DEP discharge?

I was going into the Marines and things happened, long story short my g/f came up pregnant. I tried talking to them and they would not work with me on this in anyway. I DEP discharged and went and talked to the Air Force. Now im getting stuck with a **** job due to recruiters lies. I was told by my Air Force recruiter that you can only receive a DEP discharge two times and then cannot join any branch of service. Please help!
