Girls, hello! I'm having panic and crying ? I gave birth on April 19th, C-section, the suture is healing well and seems like everything is fine, yesterday evening I discovered some kind of lump inside the suture, it doesn't hurt, it's not painful to touch either. Maybe someone had this before? Don't know if I should be worried or is it normal.
