I used to ovulate around CD15 (well I did with my first pregnancy) this cycle I’m CD18 and no positive OPK it only went dark once was that the positive just in bad tests?

I havnt had any other ovulation symptoms and have been fairly dry down there? I’m either really late ovulating or I won’t at all? I also had fertility acupuncture on CD15
