2 good follicles but no +OPK

Alayna

I took clomid 50mg for the first time days 5-9, and had an a ultrasound yesterday to check for follicles on CD14. She said I should be having positive opks now and should ovulate yesterday or today.

The sizes were 18.6mm and 22, I believe. We BD yesterday but no positive on clearblue or the cheapie test. Should I be concerned or is this normal? I’m even getting the ovulation pains that woke me up out of my sleep last night on my right side. Then this morning on my left.
