Hi there just wanted to share my PCOS story, hope it will be of some help to you.
I was diagnosed with PCOS back in 2008. I was, and still am only BMI 22, my skin is fine and I don't have excess hair etc, so you would think not a typical case. My main symptom was irregular periods. I was originally referred to a consultant for the scan and diagnosis who suggested I go on the pill (Yasmin) as I wasn't ttc at the time.
So we come to 2009 and DH and I decide to ttc and wham first month off the pill DS is conceived and all is well
so I was clearly ovulating and an OPK DID pick that up.
So we come to present day, we are ttc number 2 and have been for 10 long months
I naively thought it would be that easy second time around but no, sadly not. I started temp charting almost straight away, and used OPKs and from both of these I could see I was ovulating just really really late (CD30ish) which made for extremely long cycles.
Back in May I had a miscarriage, and since then I have had 2 chemical pregnancies so just last week I had an appointment with a private fertility clinic to go to talk to a specialist about PCOS and ttc (GP was royally useless).
What the consultant explained to me was extremely interesting. He said that the current thinking was that PCOS stems from insulin resistance which in turn causes an increase in testosterone in your body and a general imbalance in other hormones which causes ovulation issues and the other symptoms. He has prescribed Metformin which I am taking 3 times a day. He said that this will regulate my cycle by stopping the insulin resistance interfering with the hormones IYSWIM. As I said I don't have any weight issues so it wasn't prescribed for that reason - it was purely to help with ttc. He also said that he thought my early losses could have been due to the PCOS too and said that I should stay on the Metformin until 12 weeks when I do conceive again to help to reduce the mc risk.
I have also been given Clomid to take next time I get a period (if we don't manage it this cycle of course!). His explanation for this was that even though I am ovulating naturally the Clomid will encourage ovulation at a more "normal" time which apparently reduces the risk of poor quality eggs (what a horrid phrase) which are sometimes released with such late ovulation.
All in all it was money well spent - as I had previously been diagnosed I didn't need any further tests so all it took was a consultation and a prescription and hopefully we are now on our way to a successful pregnancy.
The consultant said that GPs can prescribe Metformin but many don't know much about PCOS so they are reluctant to prescribe it for that purpose unless it is clear that the patient is clearly in need of weight loss. I would push for a referral to a specialist if you can, this is a complex condition.
Anyway, sorry for rambling - bottom line is I have PCOS, I am ovulating (but late), I did conceive DS easily but I am having issues this time around, OPKs DO work even if you have PCOS (especially if combined with temp charting) and Metformin and Clomid could help even if you are ovulating naturally.
Phew, sorry that was longer than I intended.....
