Clomid and opk

So I did my first round of clomid this month cd3-7. It looks that I ovulate on my own normally. My cycles are extremely regular and my opk are usually very reliable. Its just been over 2 years ttc so were on to the next step. However, this month after the clomid, my readings have been low and I haven't seen ovulation yet. Has anyone else had this happen. At this point I almost feel like I was better off not taking the clomid. The first picture is cycle before clomid the second picture is after
