Has any one done clomid 3-7 And then 5-9 the next cycle? I did 3-7 and ovulated cd11 (four days after my last pill) progesterone test confirmed I tested at a 23. I switched to 5-9 this month in on cd 14 and very negative opks. What's going on? Has any one done this? Could I just ovulate a lot later this month? I also tested cd 11 this month (one day after last clomid pill) and got a positive.. Figured it was from the clomid but could I have actually ovulated that early?
