Sorry may be tmi..Mommies, how long did you bleed after giving birth? And when did you start your period? I'm a little concern bc it's been 10weeks postpartum and I'm still having spots of blood, it comes and goes..and definitely not period. When I went to see my ob and pcm around 6~7weeks they just told me that it's normal but I don't think it is..
