OPK Confusion

Cindy
I had a +OPK last week Wed & Thursday so I stopped testing. I was nauseous last night and decided to do another OPK since that's usually how I know I'm close to ovulating and got a positive. I confirmed it again today with a digital test and a regular one. Both are positive. 
​(I'm in CD18 and have PCOS so my periods right now are being triggered by Provera and ovulation by Clomid)
​Who else has gone through this?
