PCOS support

I need some help and information regarding Hypo-Thyroid & PCOS issues. I have been married for over a year. Ever since my puberty, I had irregular periods, had hirsutism (unwanted hair on face and other areas). Went to a gynecologist when I was in college around 5 years back and she suspected PCOS and did some tests. She said that there is chance that I might have PCOS and said she needed to run more tests to confirm it but due to various reasons I ignored it without realizing its implications.

I have irregular periods where they were absent for more than 6-7 months. I used to wait for 6-7 months and then take medicines for it.Couple of months back I went to Gyn for regular checkup and doctor diagnosed that I have HypoThyroid. Couple of days back, I have been diagnosed with PCOS. Doctor says that it's better if I plan for kids right away as it might get difficult after few years.But my husband before marriage itself told me that he wants kids only after 4 years after marriage to which I agreed.I'm 26 now which will make me 29 when we plan for kids. I told him current situation and he says there is no way he will change his plans and he says there are many ways in which I can get pregnant with present medical advancements. He says life will be hell if we have kids in haste and we should only plan when both of us are absolutely ready.

I have been researching a lot and found mixed results. Some encouraging news where they were able to have kids naturally after trying for year or two, some after lot of efforts/treatment and some just gave up after trying for years. I found lots of materials on internet about treatments, diets,tips etc,. but would like to have a direct communication with some one who has been through this situation. SO much information on internet is overwhelming and confusing me. Is it possible through forms here ?

Apart from these physical medical conditions, I have been feeling guilty around my husband. We did not tell them about my health issues before marriage(PCOS, unwanted hair) and now I find out that it's difficult to do the most important task of a wife i.e give life. Apart from that, my husband after our marriage came to know about my past affair with all the specifics.I lied to him that I had a clean past. He forgave me and loves me even though he did not have any affairs. To add to it, this PCOS thing now.

Any help would be appreciated.
