Yes you need to visit a doctor preferably a gynecologist if none of your hormonal tests were abnormal.
In case you have deranged hormonal reports, taking an opinion from an endocrinologist
is also advisable though follow up with your gynecologist should continue.
You likely have a condition called POLYCYSTIC OVARIAN SYNDROME
where in the above problems do occur.
Mainstay of treatment is weight reduction along with metformin
The other treatment involve treating the main complaint you are worried about.
If you do not wish to conceive then starting an oral contraceptive
pill is a good way of regularizing cycles.
If you wish to conceive then treatment is entirely different with ovulation induction
