A relative of mine has very few periods each year, around 3 max. She is 29, started menstruation normally during teens and then got to this situation early 20s, so thus has been the situation for several years. The doctor thinks it might bt Polycystic overy syndrome but will only test if she is attempting to become pregnant, which she isn't. Surely the doc has a duty to check/arrange tests/referral for this and she shouldn't have to wait until she wants to be pregnant.
