Temping and using opks. Confused

Kristin • TTC our rainbow 🌈 baby 👶! Miscarried 4/4/18 at 6 weeks, with our first. #Godhasbiggerplans #mommy2anAngel

I am on my second cycle of Clomid this cycle my doctor did 100mg, and I got my first ever positive ovulation test on cd 17, when temping I was told that to confirm ovulation it would be 3 consecutive days of elevated temps but my temp dropped this morning( pictures of charts below) any thoughts on why this would happen? I took the Clomid on cd 4-8, and I go this Sunday for my progesterone level. Should have those results Monday. Last month I took Clomid 50 mg cd 5-9 and didn’t get a positive ovulation test. My progesterone level was 5.8 with that cycle. 🙏 praying this cycle is it for us.
