How do you diagnose a progesterone problem?

[AndiE]

Long story short, I suspect my progesterone levels are causing me probs. Not 100pc but here's my story:
Diagnosed with pcos (though no BT or ultrasound utilised in this diagnosis) in May 2011
Prescribed 50mg Clomid - didn't make me ovulate
Increased to 100mg Clomid - first cycle I O'd on day 19 (poss day 18) on CD19 my progesterone was 5, and CD24 (5DPO) my progesterone level was 16. While I thought that was really positive, I ended up getting AF on what should have been CD28.

I can't work out how my progesterone level 5DPO can be 16 and yet AF arrives 9DPO. Obviously my hormones are playing havoc.

I'm now on my second cycle of 100mg of Clomid, and I'm just going to wait and see what happens. Naturally, in an idea world I'd ovulate on CD14 ... but who knows.

Anyway, if I get AF so soon after ovulation again, I'm going to have to get it investigated. Given my "diagnosis" of PCOS without any tests, I want an idea on what I should ask for to diagnose a progesterone issue. Is it just a case of more frequent BTs post-ovulation?

Who are you seeing right now? A proper FS or gynae?
It does sound a bit like there's a luteal phase issue.

Dammit - lost my reply (stoopid touchy laptop!). So I'll keep it brief this time round:
I'm with a gynae - I'll get a referrel to a FS if the next cycle or two is still out of whack.

I agree with MadB.

Go to a FS. Basically it will involve having blood tests during your cycle though...

Good luck!

My gyn told me that anything under 25 didn't suggest that ovulation happened. Sounds very strange to me, I'd say they will get you to have several BT throughout your cycle to confirm. Good luck!

Thanks Tasha. That's interesting. My gyn told me 10-20 indicated ovulation. I'm certain I did though, all the signs were there plus a positivie OPK (plus the blood test results).
Am waiting on my gyn to return my call today - I want her thoughts on what's happening.
