Cervical Mucous Prior To Period Can This Prevent Me From Getting Pregnant?

Can this prevent me from getting pregnant? - cervical mucous prior to period

I have cysts on my ovaries. I usually regular cycles of 27 days, but my last cycle was 32 days and ovulation CD25. Now I am on CD 18 and still not ovulate. And there is not any evidence. In general, I have cervical mucus protein 3.2 days before ovulation, but I was very dry and my throat is very small.

Can ovarian cysts are ruining my cycles and prevent or delay ovulation?
