Does anyone else check saliva for ovulation?

So confused. Last time I had ferning it was 3 days in a row. Yesterday on CD 11, I had some ferning..today CD 12..there was less and it would be "transistonal" at best.....no + opk yet..and my bbt hasn't spiked..has anyone else experienced this?

EDIT - Took picture off..uploading it severely decreased quality and you couldn't even see the small amount of ferning I had yesterday 😕
