If it makes you feel better, I had cysts and ran the gamut of tests when I was younger, have PCOS, rarely had periods (every 18-24 months tops) without birth control pills. I was told the same thing, that getting pregnant would likely be very difficult but I ended up getting pregnant fairly easy. My first I wasn't trying but my second was planned. I had my IUD removed November and I was pregnant by the end of December! Total shock as we were ready for a lot of trying.
This may not be the case for you but don't get discouraged until you find you really are having difficulty. My Ob said he didn't really look at fertility issues until someone had been trying unsuccessfully for at least a year.
Good luck to you!
