cervix help 😂

So apologies if this kinda thing grosses you out... but after knowing I have ovulated 100% for the first time ever during my 8 months of trying I have been keeping track of my cervix...
Does anyone know what to look for and what it all means?? 
It was high and open a couple of days ago and it seems to have lowered slightly since then.... iv read that if it stays high you've more than likely conceived. Any truth in this? 
Thanks all :) xxx
