Cervix questions!! Help needed!

Rebecca • Beautiful baby girl born 12th September 2018 - love my little family 👨‍👩‍👧🐶

So we've only just started TTC within the past few weeks. I've read so much on CM, BBT and all other sorts of things... the one thing I still struggle with is the position of my cervix! I know when it's high low soft hard, but WHAT does this MEANNNN?? I was on the pill til a month ago so I'm aware my cycle may be off, and it's been that long I can't remember the length of my cycles (feeling it might have been between 24 and 28 days). I had my withdrawal bleed and then 1 week later my period from 20th to 23rd August, but this morning when checking my cervix it was fairly soft but definitely high! So now I'm confused as I thought this wouldn't happen for a few days yet!!?? please help! Thank you in advance :)
