I am on cd16 and STILL spotting. It is very light. This is my third clomid cycle and I was hoping I would ovulate this time. I am using opks (I started on cd10). This is the first time I've used them on a clomid cycle. The line is darker than when I started but it's not positive yet. My doctor had written this cycle off because of my long af. I can't find anything on the Internet about ovulating while on clomid after a long af. Anyone have experience with anything like this. I took my last pill last Wednesday at 9 pm. So it's been a little over a week since my last dose. It was 150mg for 5 days.
