All. I have been bleeding since week 7 of my pregnancy. The Consultant thinks it is implantation problems (as per letter I received today although she didn't mention this when I saw her). Has anyone had this? I have passed one huge clot and at last scan there was another one 4 x 2 x 2 cms. Also there is an area of fluid around sac 2 x 1 x 2 cms. Just want to know if anyone has experienced this and whether they'd previously had a c-section. I've read on net that the scar tissue can cause placenta implantation issues in subsequent pregnancices.
