Confused.... help please!!

Okay, so last month I had a really odd short cycle, like 20 days. So this month I started doing ovulation tests early to know for sure when I ovulate. Nothing has screamed positive at me yet and I've been getting flashing smiley on clear blue digital for the last 7 days, testing twice a day with them the last few days. Do you think its possible I missed when i ovulated? Cervix was high for the first time today all cycle and had watery cm al day...
