Thanks I thought it might have happened today because of the pains I had and because 7dpo is a bit more in the 'normal' range than 5 (apparently).

Just got back from seeing the doc with a big grin on my face. My progesterone (in a cycle with no meds whatsoever) was 55 at my cd21 BT! LAst time I had it checked it was only 7, meaning that O hadnt even happened! Woo hoo!
