3 Low LH test 1 Peak, now Low!?!

Natasha💛

Ladies, I was supposed to be in my fertile window Sunday-tomorrow. I took Clearblue OPK S,M,T all we’re low. Yesterday (Wednesday) it was Peak! This morning I took it and it’s back to low. I defiantly feel like I ovulated yesterday due to cramps and lots of “twinges.” I’m so confused, any insight on this?
