Dpo and bfp???

Charlie • Hi everyone! Trying to conceive baby number one.
Hi ladies, i was just wondering, what dpo were you when you got your bfp
​Im 9 dpo, amd due my AF on the 26th ive been taking tests but all bfn, am i testing too early? 
​What dpo would it start to show on a test? I asked my mum for advice a d she thinks i should wait till at least june 5th to test and get an accurate answer.
​Any help would be good! 
​Thank you
