Period coming or implantation?

Okay, so technically I'm "2 weeks late" on the flo app. BUT this is only my second period post partum and I've heard they can be irregular.

Now the smily face bleeding was yesterday. Before that picture there was a bit more blood mixed with mucous like discharge.

The other photo is today. I thought my period was coming yesterday but then I had absolutely nothing until that little bit today.

Any opinions?
