What is this ?

I’m currently breastfeeding my 8 month old and was due for my period yesterday and nothing.. but I have this cm. What does this mean ?& no I’m not pregnant but I’m looking to start trying this month because I was expecting my period but i haven’t started my period this month. Can I still try ? Am I still ovulating even if I miss this cycles period ? Doesn’t this look like fertile cm ? It’s been a month since I had my first period since giving birth.
