No one usually

No one on this app usually helps me but I really need help. I've been trying to conceive for about 2 years. And nothing has happened. Instead I go months without AF showing up. I saw an OB July and all she told me was I have borderline PCOS to exercise and watch what I eat. Told me to take prenatal vitamins and vitamin D supplements. And she put me on birth control for 3 months. No one I have talked to even knows what borderline PCOS is. Should I seek a new OB? I just got off my birth control not long ago.
