OPK ISSUE - HELP

Jamie • 26 years old with 2 beautiful daughters ages 5&8! Married and TTC for 2 years!
SO I've been getting "highly fertile" for 6 days and last night before bed I took an extra test to make sure I didn't miss "peak" and so I took one this morning and it's "low" I'm so discouraged and confused :/ Does this mean I'm not ovulating ????
