10dpo with FRER can I take it w/o morning urin ?

I am so impatient I saw so many BFP in 10dpo but does the first morning urine matter. I really wanna surprise DH before he come from work. But idk I dont want to waste a FRER because they are kind of expensive and I got a BFN at 9dpo. But so many people get theres on 10dpo 😭
