I've had tons of blood work done. It all confirms that I'm not ovulating, and that I've got PCOS. The bloods showed signs of PCOS (some sort of hormones were out of wack), and the scan actually showed a polysistic ovary. My cholesterol levels are slightly high, but only slightly and nothing to worry about and blood pressure (130/80) is fine, bloods showed I'm not ovulating. No diabetes or any of the other things they check for.
So for now the gynae thinks it's PCOS that's not helping things along, but he wants me to lose some weight (hence why he said I won't need to actually go to my recommended BMI) as it does often help women with PCOS start ovulating on their own. He's still hopeful for that. Once I've lost weight and see him, or someone else, again in 2 months and I'm still not ovulating he will concider Clomid or Metformin to help me speed things up a little. But, as at the moment I've 'only' been trying for 10 months, he won't give me Clomid yet.
Twins sound good though!! I'm actually hoping that once I do start ovulating I'll ovulate more than one egg so I'll conceive multiples

That is one of the 'risks' of Metformin that the gynae brought up, the chance of over stimulation. Which I did already know, and to be honest ... it's not something I'd want to go through! To know you've got perfect eggs there that could make you pregnant, but you're better off not using them as you might end up with say, 8 children. What a horrible choice to make.
Twins however, conceived naturally ... yes please!
