First cycle with clomid and ovulation help

Alexandria • Wife 7/3/11💍 Mommy to Mila 2/20/19 👧🏻 + Eleanor 11/23/21 👶🏻

This is my first cycle taking 1700mg of metformin and 50mg of clomid 3-7. It’s cd 11 and it’s the first time in 2 weeks I have been feeling frisky. No ewcm and I track my ovulation with ferning and opks. I didn’t have any ferns this morning but my opk looks positive. Should I got by the opk or fern test?
