What is the chance of a girl getting pregnant if a guy has not ejaculated or has not had any sex in 7 months?

You have the chance any other girl would have. Just becasue you don't have sex doesn't mean it's going to cause you not to have a baby, and obviously if a guy doesn't ejaculate in you your not going to get pregnant, but there are risk out there to where you can just have sperm rubbed on your vagina and you can get pregnant!
