How do I delete posts?

Lori
I miscarried today and I want to delete some posts of my positive tests. I can't figure it out maybe it's to early to be fooling with it so soon. I already unistalled the Glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> App... The little pic was messing with me...
