How many DPO were you when you got your BFP?

I am 9 dpo and experiencing some pregnancy symptoms, most noticably an "off" stomach for the past 4 days. How many DPO were you when you got your BFP? I am so tempted to test, but don't want to be discouraged with a negative. I am charting and my temps are high. I tested at 14 dpo with my first pregnancy and got the positive. Just want to hear everyone's answers-- also, I will be using the First Response tests in the pink box.
