Clear blue digital opk

I’ve used this many times in the past. But can someone explain to me why I’m always getting a flashy smiley face?! It feels like my fertile window goes on for weeks (I’m on day 5 of testing and CD 13) my cycle is like clock work and I always ovulate around cd14-16. My other test are very faint lines for ovulation and feels like it’s not coming ☹️

I’ve been trying for over 2 years with 2 back to back miscarriages. This cycle I’m doing acupuncture again with the help of Chinese medicine (she made me some herbs to drink twice a day). I’ve noticed I haven’t gotten my “egg white” mucus this month I’m and a little disappointed.

Looking for thoughts and opinions!
