OPK - first round clomid 100mg

This is suppose to be my “predicted” ovulation day and I’ve been getting these since cycle day 9 no progress since (it’s cycle day 17). I had my ultrasound follow up and I guess none of the follicles didn’t even get over 10. It’s only my first round with clomid, I was starting at 100mg and I will be bumped up to 150mg. Bright side is my uterine lining thickened which is good, it’s 6mm before it was 2mm. I’m just really trying not to get discouraged so early as it is the beginning of our journey to TTC. Any success stories with you ladies that didn’t have mature follicles in the beginning but made progress after your other rounds?? I just need to see/hear the light of this
