You can see your doctor before you start trying for a preconception checkup. I suggest that. They run some blood tests and make sure you are in good health for ttc (chicken pox and rhubella are the biggies) and they will write you a script for prenatal vitamins.
I'm currently ttc with pcos, so you will have company when you and your dh decide to start ttc.
there are many medications available now to help with the condition. You will need to wait until you get some bloodwork done for the doctors to decide what will be best for you. Metformin is usually the "go to" med. It helps regulate some hormones, but you may not have to take that, it will just all depend.
Not everyone with pcos has difficulty conceiving. You will just have to wait and see.
Good luck and congrats on the upcoming wedding!
