When to test!!!

Brittany

AF is due the 6th. I think I ovulated on the 15th. Glo says I did on the 18? Either way when should I test. I feel so new to this all over again. We tried three years for my son. And I’m on the band wagon to try for number two. (My son turns one in April and. I don’t want a huge gap if it takes three years again) any ways! When do I test lol. HMU!!!
