Confused about my ovulation

Sarah

So I've come off the pill to TTC. This is my first cycle off it. I'm tracking my cm and cervix position. I think I'm having my show and as such would be about to ovulate I think from what I've researched? My chart on here says my fertile window doesn't even start til tomorrow the 18th and I won't ovulate til the 23rd October. Not sure what to do? Help!
