Once again my body has thrown me a curve ball. Age 45, 8th round of Clomid 2nd round at 150mg, days 5-9. Started testing at CD12 with Clearblue dual hormone. Blank circles up until CD16 then i got my flashing smiley, i then had 8 flashing smileys upto CD23. I tested FMU today and another flashing smiley but then i noticed that AF had started. I took another OPK test SMU and the line i think is darker than it should be.I`m struggling to understand my body. Does anybody have experience of this, 24 days is a very short cycle, surely my Estrogen level should have dropped and Clearblue OPK should had gone to a blank circle again?
