I'd love some advice from you gorgeous girlies please!!!

I have PCOS but I have only been made aware of it in recent months. DH and I are TTC #2 but I am finding it impossible to know when I ovulate etc as my periods have become irregular again. AF was due last Thursday and I still haven't got it. I had done 4 pg tests all which are negative and I have AF cramps to boot.

Why does this have to be SOOO hard?!? Do I have to be trying for 6-12 months before the Dr will give me anything like Clomid? Or considering my "problems" are they likely to give me something sooner rather than later?

TIA.. From a rather confuzzled and stressed out chicky!!
