Am I fertile?

I've been on a few different types of birth control for the last 5-6 years... I recently stopped using the ring as of August this year in hopes that I have not become sterile... How long should it take before I am ovulating regularly again or is it possible I have ruined all chances of ever becoming pregnant by being on birth control for so long? Also I cannot have a pap done to find out because I am not 21 yet
