New to TTC , need advice on my fertile window

Sorry I know this is TMI, I’m using Lh test strips and will start bbt soon but haven’t started yet. My Lh is now rising, I’m cycle day 15 as my period started the 25th. Predicted ovulation from the apps is the 14th or 15th. Anyways now that there’s some info- my dilemma !! So I’m worried I already ovulated going off of my Cm being creamy white like this? What do you ladies think? This is the first day this month that I’ve had it in my underwear like this ( definitely not normal so it either means I’m about to ovulate, currently ovulation , or already happened.
