Thank you viroids for your posts towards of the last Fred.
I'm still not sure on how to react to the news that there is a strong chance I have PCOS. I feel more able to post a longer post than I did last night though.
Tink I'm not sure what my progesterone result was. She told me she wasn't too worried by my hormone results other than LH being slightly high and testosterone being too high. As for actual numbers of anything I'm not sure what they were. She showed me them on screen and I meant to ask for a print out as I know some of the lovely ladies on here could have helped me with the numbers, but I was focusing on not crying in the doctors and forgot... 
How can I check if I am icing?
I haven't been doing OPKs regularly - but when I have used them (ICs) I have always got a negative result. Mostly they are completely blank (other than control line), but I did get faint second lines a while ago now. I also had ewcm around the same time. I'm hoping that's a positive sign. But that was like a month ago or so now anyway. I also had that short light bleed on 17th/18th Nov.
As for other symptoms the only real one I have is my weight. I really struggle to lose weight - It seems that despite eating relatively healthily and trying to exercise I can't seem to lose anything. When I'm being extremely strict I drop a couple of pounds, but I can't keep up the extremely strict-ness all the time. I'm rubbish.
The doctor suggested ensuring that I am eating a lot of low GI foods, so I need to go and research this. I already eat things like wholemeal bread, wholemeal pasta, etc. but I still eat what I'm guessing is too much of things like breads, pastas, rice, etc.
I should be getting a date for an ultrasound scan in the post.
Oh, and the doctor also suggested that I start taking metformin. Starting at one 500mg tablet a day for the first week, 2 tablets a day the second week, and 3 a day from the third week onwards.
We've had friends staying this weekend - including a 3 year old. I found that particularly hard to deal with. Especially DH being around her. In my head I had it that we're never going to have kids, and seeing him playing with her just made me cry. Possible overreaction I admit but I couldn't help it.
