First time using opk

Carissa • Tue, Dec 25 • Mommy to a 3yr old girl and pregnant with baby #2🤰🏻

I know this is a neg opk but it’s my first time ever taking one. Do I take them once every day at the same time or twice a day? Does it look like I’ll ovulate soon? I am coming off birth control going on a month now and I haven’t had a withdrawal bleed or a period
