When to Test? Help Please!!!

JS

Hello Everyone, I am new at ttc and this is my first month tracking my ovulation. I bought two types of tests. The traditional strips with the lines and the advanced digital ones that track estrogen and LH levels.

My question is- when during the day do I test? The strips say on the instructions to test during the day 10am-8pm not morning urine. BUT the digital test says on instructions morning urine is best!!

Help!!! Why are they different? And which one is best?

Thank you sooo much!
