Please helppp .. ( ovulation question )

So I'm on cycle day 12 and my cycle is 30 days ...I've been checking my cm these past days .. I noticed this morning I had eggwhite cm but now (afternoon) just whitish/clear non stretchy cm .. according to all my apps I shouldn't ovulate until Friday ... do you ladies think this normal couple days before ovulation ? When do you ladies start baby dancing ? Thank you in advance
