  • Gestational Sac but No Embryo

    QUESTION

    Dear Midwife,
    Two years ago I had an ectopic pregnancy, then just Jan 1st I had a miscarriage (very early pregnancy) and now I have tested positive for pregnancy again.

  • First Trimester Changes

    At the time of conception an egg is fertilized, thereby creating a unique new cell. The cell divides very quickly into many more cells and at about 1 week after conception this tiny mass of cells attach itself to the wall of the uterus (implantation).

  • Scientists Discover What Makes Human Embryo Attach to Uterus

    A UCSF-led research team has identified the first molecular step that allows a week-old human embryo to attach to the uterus. The finding is expected to provide a new tool to diagnose and treat infertility and early pregnancy loss, the scientists report.

    The researchers found convincing evidence that a molecular sticking process stops the embryo's journey along the uterine wall and starts attaching it to the wall -- the first stage of implantation. Failure of the embryo to implant causes about three-fourths of lost pregnancies.
