Best time to test with OPK?

Ashlee • Married my high school sweetheart. Had our little lady 3.16.2016 💜 Had our little man 3.27.2018 💙 Teaches HS English

I've read so many different things about the best time to test. Some say AM, some say mid-day, but everything says whatever time you choose, be consistent. Any advice from those that use OPK??
