No lh surge day before ovulation predicted

Pandy
I have been taking an opk everyday for the past few days. If i am tracking properly i should be ovulating tomorrow but there still hasn't been even a faint double line on the opk. I am starting to lose hope. This is my first time actually ttc. I already have 2 little ones. But i really want a baby with my new husband. Has anyone had this problem with no lh? Should i be planning to go to dr? Im going to test again tomorrow but im getting nervous.
