Getting A Little Discouraged ladies :( BFN at 8-9 DPO...?

Hi Ladies,I was soo anxious to test today so i did lol...and of course a B F N....I am Only 8-9 DPO,but i was thinking i should at least see a faiint Line!?! So I dont know,im still hanging on to hope...I really dont have that many symptoms,I had Some Light PMS cramping at 5-6 dpo and since 7 dpo my are a little sore,not much,having headaches..thats all. So I was wondering have any of you ladies tested at 8-9 dpo and Got a Neg..then later on got a Positive? How many days past O did you get your BFP?? Thanks ladies! just need some Encouragement! Good Luck & Baby dust to all TTC!!
