Can someone explain to me how it was when they experienced their Implantation Bleeding.? Cuz I'm not sure if that's what I'm having. This morning at work, I went to the bathroom, and you know I wiped myself, and it was a really brownish color. Go home, went to bed, woke up and went to the bathroom and same thing, because if it was my period I would usually start bleeding after the first wipe I saw this morning. I feel a slight cramping, and a slight nauseous right now.. 😓
