CM in case of pregnancy or before period

Christine

Hi ! I was wondering how the CM change days before period VS first days of pregnancy

I’m suppose to start my period today or tomorrow and I have white-ish watery discharge (more than I normally have I think)

One source tells me that days before the period there’s supposed to be less CM

Another source tells me the opposite 🤷‍♀️

So I don’t know what to think and I’m really hoping to be pregnant 🥲
