What tests are best?!

Samantha

Hey ladies, I’m 11 dpo and wondering 2 things. 1) how long should I hold my urine before testing? (Worked a night shift last night and can’t sleep so trying to hold it as I drink a lot of water). And 2) what tests do you find the most sensitive. I find FRER’s have been giving me indents!! And I do follow the instructions so I’m confused. Should I keep trying with FRER? Are they the most sensitive? I’m 2 days before expected period. Do I still have a chance?
