I had the implantation bleeding at 4 weeks, which is when I found out I was pregnant again. The
bleeding went away for about a week
and has been back for about a week to a week
and a half. It is dark red, what I have been told is `old, dried blood`. I have told my Dr and she doesn`t seem concerned. I have a sonogram on Monday, but today I started bleeding a bit more. Nothing to fill more than a liner, but enough to make me worry. How normal is this?
