negative but positive

so i had light spotting last week, and thought well maybe i'm pregnant??? so i took a hpt this morning...negative. so then i logged on here and somebody said something about fertility friend...so i logged on there, added all my info, and it says i could be fertile towards the end of this week. so i did a opt, also negative. but i'll keep it up for the next week or so and hopefully i get a positive lh surge!! (my last AF was august 25) baby dust to me!!!
