Quoting ZanesMommy2011:" I thought my positive lines should've been darker today and they're the same if not a little fainter. ... [snip!] ... to everything I implanted yesterday and ik that's when HCG is released so maybe that's why yesterday's BFP were more prominent?"
it took me a good 4-5 days to finnaly get nice dark lines, they were always just a smidge darker or lighter... also my FMU was never as dark as later in the day lik in the afternoon. If i were you id get some FRER and some DS tests... and test lol..
watch yourlines...but I know its very hard not to over analyze tests and line darkness...even later on my lines were never crazy dark like they were with my 2nd and 3rd babies.
