Good luck at the doctor!
Like everyone else said, PCOS is not the end of the world. It's definitely a downer when you first find out, but for me- it kind of put me at ease. I finally had a REASON for all of my weird issues! After (IF!) you get a diagnosis, don't let it get you down- focus on what you can do now to start working on issues that may be a problem later!
I've seen it time and time again (and in myself as well)... but if you lose your excess weight, often the symptoms reduce or disappear completely! Unfortunately those of us "blessed" with it typically have a harder time losing weight, but it's not impossible! Actually here's a fun fact that I literally just learned moments ago and has ME even more motivated: Jillian Michaels has PCOS! I had no idea! One look at her can just show you that it's possible to have it and be in shape.
Also, in terms of your symptoms: I've always heard that PCOS is called a "syndrome" because you do not need to have all of the symptoms. Women can have a mixture of the standard symptoms... some have all, some have none just about. I have irregular cycles, weight issues, and insulin resistance. I do not have acne, the excess hair, no thinning hair, dark spots, etc. My testosterone level is fairly normal, per my doctor. As a matter of fact, I just took the PCOS quiz posted by astrophe, and it told me that it was NOT likely that I have PCOS! lol (I assure you that I do: I have had blood work, ultrasounds, etc. to prove it)
As far as children go-- like everyone said, it's possible to have kids with PCOS. Sometimes it takes a little help, but there are definitely those of us in the PCOS community who have conceived naturally!
I have a beautiful 21 month old boy that was completely natural and a little miracle.
And Metformin is a blessing! Might tear your stomach up at first but I love having myself regulated. It also helps with the weight loss!!! Another perk: If you don't have insurance, Metformin is sold in Walmart's pharmacy very cheap!
