Anyone know what this is?

TMI …..

Does anyone know what this is?

I went to the toilet cause it felt quite wet down there and noticed this on my knickers but when I wiped it was just clear watery cm.

We are ttc but not tracking ovulation and I’m on CD 14 which on some apps says I’m ovulating but my periods are quite irregular so it’s hard to know when I’m going to start my period.

This was later on in the day after I wiped ( first photo)
