Spotting / OPK Question !!!! ????

Layla • Mammy to Sophia, who was 2 in June 💕 had a mmc end of Nov 18 😢, Pregnant with 🌈 👶🏼 💙 .. 👨‍👩‍👧 + 🌈👶🏼💙 EDD 12/11/19 🤞🏼💕

Ladies I’m 9 weeks post D&C after mmc, was in limbo with my cycle but got 2 pos opk’s on Thurs and Sat just gone and nearly pos on the Fri (my urine could have been diluted)

I had ovary type twinges though around the time of pos opk’s and today I have had a tiny bit of brown spotting only when I wipe!

Is it normal to get pos opk’s if AF is on the way!! 🤔🤔🤔🤔
