I'm going to try my best to wait til af is due

I know myself, if I go to the store tomorrow and buy tests, I'll spend $12 and buy a 3 pack and I wont be able to resist peeing on them for the next 3 days... and it would be too early, so they would definitely all be negative so i'd end up buying another 3 pack next week... and $24 in tests in one month is just unnecessary!
thanks for all the input... and here's hoping for bfp ... i dunno how many months of this i can take!!
