Follicle scan: Anyone?

Jessica • PCOS - Step mom of two fantastic kids, momma to a 3 yr old boy, and currently due with a baby girl April 2020 💕
Doing timed intercourse this cycle, Did 100mg clomid day 5-9 and went this morning for my follicle scan (CD12) and I had one that was 10cm and another that was 13cm and several other smaller ones all on my right, nothing on the left. They told me to come back on Monday for another scan to see if they're big enough for trigger shot. Anyone had any experience with this? Anyone had follicles that were too small but then grew big enough for the trigger? I just don't know how to feel about this, discouraged or hopeful?
