I would definitely try a different GP, or ask to be referred to a specialist. It doesn't sound like your GP has any intention of taking the situation seriously.
I have PCOS, and was put on Metformin (a drug used to treat diabetes), and also started taking Agnus Castus. I was suddenly able to lose weight (as the Met fixed the insulin resistance) and I went from having no periods to having a 28-31 day cycle. Day 21 progesterone tests showed that I was ovulating.
We were then told we'd need ICSI as my DH's results weren't that great, and given a less than 1% chance of conceiving naturally. The Monday after our ICSI screening appointment, I found out I was pregnant - so much for their statistics!
PCOS is a manageable condition, but you do need to have a doctor who recognises the impact it can have. Quite apart from fertility issues, the endocrine problem that's part of the syndrome can lead to other, serious conditions. It's ridiculous when you think that between 1 in 5 and 1 in 10 women will have it, and GPs still don't take it seriously!
Interestingly, it's possible to have the syndrome (pcoS) without having cysts on your ovaries. And you can have polycystic ovaries (PCO) without having the syndrome - which is why some ladies don't have any symptoms.
One thing which is worth mentioning is that home ovulation tests (which work by testing for the LH surge) are not reliable for women with PCOS, normally
. Our hormones tend to be so out of whack that the tests just don't work well. I'm not sure if this still applies if you're on any kind of treatment to balance out hormone levels (like Met), but I generally avoided them anyway. I could tell by saliva (under a microscope) and CM if I was ovulating, in the end
Good luck, and try not to worry too much. I've got lots of friends with PCOS, and I'm the 4th or 5th to conceive - some had fertility treatment (from clomid to IVF), and some (like me) had a miracle natural conception. You'll get there
