Clomid no ovulation 😔

Melissa
Currently on CD 21 with no positive ovulation test in sight. This is my first cycle on 50 mg Clomid (cd 5-9). I started testing for ovulation on cd 10. The thing is, my cycles are all over the place. One month it's 20 days, the next it's 47. I have to go in to get blood work done today to see if I OV but I feel like it's a waste of time. I haven't had any EWCM....just watery. Has anyone else experienced this? I've been using the clear blue advanced digital and have gotten the flashing smiley for 11 days now (high fertility). Help!Â
