Cervix position and softness?

Low soft cervix means you’re about to start your period right?? Or getting ready to? I’m due for it any time now. I got curious and checked it earlier and it was high and soft. Checked it again and it was low. Im just curious about it 🤣 Im also having really thin, watery discharge. Which I know doesn’t technically mean anything in particular. Just thought I’d add that in there lol. I know I’ve been pmsing like crazy this month. Mood swings, sore breasts, nausea, sensitive to smells, bloating.. ya know, all the normal stuffs 🤣 crazy how our bodies work!
