16-9-2009 - Don't know what to think

My mood while writing this blog: confused

I am so confused. I took clomid on day 2-6 and I believe you can ovulate 5-10 days from your last pill. I was using opk from around cd 9, on day 13 I got a faint test line so still negative. I went for a scan on cd 14 which only showed a small follicle not big enough to produce an egg. The nurse did say that she may have missed it if I o'd earlier but I havn't had any symptoms or test to show that I have. Feeling disappointed gave up on the opk. Carried on charting with fertility friend which was showing I o'd on cycle day 12 if I didn't input neg opk. Today I put my temp in and it says Your ovulation day was moved from Cycle Day 12 to Cycle Day 16. The only cramping that I have had were on cd 16 I have had no cm at all. Can someone please advise me what may be happening. This is the link to my chart http://fertilityfriend.com/home/296620
