PPD or just normal Depression?

Is it possible to suffer from PPD after a miscarriage? I haven’t been myself since December and recently realized I was getting bad (to the point of my hair was matted since it hasn’t been brushed in a week and took 60+ minutes to brush out). I haven’t suffered from depression since middle school so I’m wondering if this could be PPD?

Just a lot of day dreaming and not really living if that makes sense.
