Testing time, am i ready yet?

Charlie • Hi everyone! Trying to conceive baby number one.
Hi ladies, 
​Im due to start my AF on the 26th so 2 days away and im 11dpo today 
​I was wondering if tomorrow might be a good time to test and if so would it be an accurate result?
​Tomorrow i will be 12dpo and it will be the day before my period.
​What to you think?
​Thank you
