I am 16 and have really bad pelvic pain since i was 12 what should i do i also have irregular periods how do i tell mom what would gyno do about this?

See OB/GYN: Your profile states you're 43 years old, and then your question states you're 16 years old. So that leaves a question as to which doctor you should be seeing. If you're 16 years old, you should be seeing your pediatrician to discuss this. Having pelvic pain for four years is not normal. This has to be evaluated further along with your irregular periods. Until a complete gynecological, pelvic, and abdominal exams are done, it's difficult to determine a proper diagnosis.
