I have PCOS and in December was put on metformin. My cycles have begun to regulate. I was beginnging to get all excited this month about doing a test so I want your thoughts on my cycles. January cycle 12/01/2011 CD1 - Ov'd CD 21 - 38 day cycle Febrary cycle 19/02/2011 CD1 - Ov'd CD 21 - 37 day cycle March cycle 28/03/2011 CD1 - OV'd CD 23 - 39 day cycle May cycle 06/05/2011 CD1 - OV'd CD 19 (acupuncture working to shorten follicular phase). So assumed my cycle would be 4 days earlier so a 34-35 day cycle. I am currently CD 34 and was planning on not testing as I thought last week I was out of the game. I started getting spots (which I normally get a few days before AF), then I had AF like cramps. But then I started getting hopeful becuase..... I got a cold sore! Absurd I know but I rarely get cold sores. Then yesterday my left boob was a bit sore and sensitive (stopped now!) and AF type cramps completely went away. Then today out of know-where I got a sydden sever cramp which I thought was AF starting but ended up dashing to the loo with diarrhorea (sorry tmi!). Afterwards the pain went away and I can't tell if I have AF cramps anymore or not. Been having hot flushes too. So I am suddenly trying to work out whether to test or not and when. If the longest cycle was 39 days then 4 days earlier is 35 days which is tomorrow. Should I test? Should I wait until Friday? Am I talking myself into symptoms that aren't really there? I guess I should test to put my mind at rest but I am fed up of the emotional rollercoaster each month. I don't do BBT becuase I found it made me more stressed. I am holding out hope that this is the month becuase we were on holiday when I Ov'd and I was lovely and relaxed. Any thoughts?
