Hi tremelo
re this part of your comment:-
"Many women with PCOS do ovulate. Whether late or irregular ovulation results in a healthy pregnancy is a separate issue, obviously"
True re the first sentence (even I ovulated once or twice she writes in amazement) but usually it is only occasional and in my case tests showed non ovulation more often than ovulation.
There is evidence to suggest that very high LH levels can be implicated in miscarriage. I was told by my cons at the time that my own personal risk of miscarriage was over 50% due to this (I had continually high LH levels compared to that of FSH which stayed consistently low). Clomid was of no benefit to me at all due to my LH levels (clomid can encourage further LH to be produced and this was clearly something I did not need) and I ended up having laparoscopic ovarian diathermy. This kickstarted ovulation in my case and it was successful. However, the cystic follicles do return over time.
As you rightly state as well charting ovulation is problematic if PCOS is an issue. The surest way I knew whether I was ovulating or not was to have regular blood tests done over a period of some months. This was also useful in that it showed clearly defined hormonal imbalances with hormone levels hardly changing.
I will offer this suggestion as well. If you are offered clomid later on in the year do ensure that you are monitored whilst on it. No monitoring is completely unacceptable as you will have no idea then whether its doing what its supposed to. Clomid's main job is to make the ovaries work harder. Do not let the GP prescribe it to you, it should be given under proper gynae supervision.
Are your day 2 tests okay?. Have they properly compared both LH and FSH levels?.
You may also find following a low GI/glycaemic load eating plan helpful in the longer term as this is more sustainable to follow.
Good luck to you and all on this thread.
