cysts

I don't have any symptoms of PCOS but they found multiple small cysts in my ovaries during ovulation. I ovulate monthly, and have regular periods. Does anyone know if this could effect my fertility? Cancerous? Could it be mistaken for early pregnancy ? The dr won't give me any answers . Also, I used to have more "normal" CM , but the past 6 months or so it's just been either dry, or slightly watery. Does anyone have answers for me? It's so stressful😭
