i tried for abt 6 mths. tough work, but strike when we kind of "give up" & in relax mode & not doing those pillows under legs for 15 mins stuff, etc.. instead, i went urinate almost immediately then went to bed.
i got my BFP from Eu Yang Sang as well

think it's best to follow the chart. if urs is regular, even better cos dun need to waste too many.
for me, that time i scared i'll end up with not enuff to use (cos my cycle difference too wide) so i kind of waited till i see watery CM. luckily din miss the boat!!

usu, can test for pregnancy when u'r 18 DPO, unless of cos, ur AF is so irregular that it comes only every 2~3 mths type, then will not be accurate lor.
