The six Days earlier pregnancy test

Meghan

So I can supposedly do a pregnancy test in 6 days but I was wondering the success rate on the first response 6 days earlier pregnancy test?? I really want to test this TWW is killing me! I'm like 6-7dpo & I have sore breasts, sore lower back, frequently urination especially at night, headaches, so many things that don't happen to me usually. But I hate testing and getting that BFN! Ugh! So tell me your experience with this pregnancy test!
