Can an opk be wrong

Ok so I had ewcm the 19th then watery until like yesterday now its white watery ish but kinda sticky with some little pieces. So I thought I already ovulated but my opks are getting darker so that would mean I'm ovulating soon. I'm so confused! My cervix is still high but it's tilted now and doesn't really feel open and it's not as soft as it was when I had watery and ewcm.
