So this is something I see alot on here, people post faint tests and people comment and say "looks faint try testing again tomorrow using fmu" but I thought I took 3 days for your urine to double up on the HCG ? So wouldn't testing the very next day not make a difference if it takes three days? Lol no hate comments please I'm just curious because maybe I was told wrong about the HCG 3 day thing? 😊😊
