Hello ? Girls, how were your first periods after childbirth? God, I haven't known what was happening for four days ? I was in pain, my lower back, my head, everything spun, I was angry at everyone, I felt like a bad dog.((( This is crazy. And today evening started bleeding, I got scared when I saw on underwear, forgot what it was ? How was it for you all? Are these symptoms normal? It's just that before I had painless ones, only a slight ache in my abdomen and that was it.
