ok so how longdid it take for your bfp to show up on preg test and was it the same each time?

im CD34 now 16DP assumed O tested on tuesday neg tested this am i thought i could see a faint line but im just gonna say it was neg cause i dont think eye squinting counts.

with ds i got a strong pos at about CD 29 less than 14 days after O suddenly my tww has turned into a three week wait as if 2 wasnt bad enough
