TTC over 2 years

My husband and I have been TTC since we got married 10/11/15, and still no pregnancy. Also I just found out I have PCOS which is most likely contributing. I was just put on metformin and hoping that will help, but really starting to get discouraged and depressed that I might not be able to have a baby. Im also going to try essential oils. I've wanted to get pregnant more than anything for so many years. And I'm not getting any younger, will be 31 in a couple months. Is there any of you who are going through or have been through this that would understand and maybe be able to give tips or encouragement? Thanks for letting me get this out :)
