Anyone's follicle shrink before trigger?

Brandi

Hey ladies! I recently posted asking about the trigger shot. I was supposed to get it today after my Follicle scan this morning. Unfortunately my Follicle shrank to a 16 instead of growing past the 17 that it was at the day before. I e never heard of this happening.. anyone else have this experience before the trigger? Pretty sure I won't ovulate on my own either. I don't even have the CM for it.. bummed but thankful. Let me know if you've had this happen before or how your trigger experience went.
