You're taking the best next step which is seeing your OB/GYN for further evaluation. They'll be in the best position to help figure out what type of cyst it is and guide you on treatment options depending on your particular situation, age, other medical conditions.
Not sure how much your pcp was able to tell you about the cyst or what the rest of your history is, but it's good to know that the majority of cysts are benign! So best next step is definitely working with your OB/GYN to get a fuller workup and more information.
As a starting point, here's some things to consider asking:
What kind of tests might I need?
Do ovarian cysts usually go away on their own, or will I need treatment? Do I need to have it removed immediately, or can we "watch and wait" for one to two months?
How much of my ovary might be removed along with the cyst, and how would this affect my fertility?
What did the pathologist's report say about the cyst?
What are the chances that the cyst will recur, or that another cyst will form?
