Posted this already but advice pls

I didn't write down when I got my first period after having my son and when it ended I so I haven't gotten one this month at all yet just finding it hard to work things out. I thought I was pregnant because I've been having a lot of symptoms then thought I was ovulating. I've been having a lot of discharge for the past 3 weeks it's been creamy not stretchy, yesterday it was like wet and slippery not stretchy. Today I got up off my sofa and felt something come out of me I thought it was my period but I checked and it was this type of cm what does this mean?
