Maybe a silly question

if your getting CM does it mean cervix is open or closed? ... as my cervix is high and I'm getting a watery slightly creamy discharge on my finger as I pulled finger out after checking positioning of cervix ... but can't tell if it's open or closed it feels like a slit but I've read pregnancy and Labour changes the way your cervix opening feels and I've had 2 babies ... I've also read if you can get a finger into it it's open however where my cervix is high I can get my finger (middle finger) far enough up to even try to get it in I can only just feel the slit ... thoughts?
