I am 20 years old and have never menstrated regularky is there something wrong with me? I have tried birth control and it didn't regulate them either.

See a doctor. The average age for menstruation to begin is 12.6 years old. There are many different factors that could cause delayed menstruation, and it would be a good idea to get a full evaluation by a physician. You might need a physical exam, blood test and possibly imaging studies. Good luck.
See a GYN. You need to see a gyn md for a "reproductive system" check. There could be many possible causes.
