Advice about PCOS, off pill for a month TTC

Hi everyone,

I'm looking for some advice about PCOS.
I found out I have PCOS in 2009 and have been on the pill ginette since then.
I came off the pill in July and my husband and I have begun to TTC.
I thought I had a few pregnancy symptoms but totally not sure now and had a BFN yesterday.
I'm on CD32 and before I was diagnosed I had pretty regular periods just a bit more than 28 days.

I'm just wondering how long my period should be late for before I should go to my doctor?

I do keep active and try to eat well, most of the time!

Any advice would be great, I feel like I'm going a bit crazy!
