Pre-implantion Pregnancy Loss is a cause of recurrent pregnancy loss. One cause is that there is either a problem with the embryo that caused trouble with it implanting. Another common cause is that the endometrium does not provide a good environment for implantation.

Since it is "pre-implantation" pregnancy loss, you often do not actually know that you are pregnant, and may just start your period a little bit late.

The treatment depends on the cause and can include anything from donor sperm, egg or empbryo, surgery, hormonal medications an dimmunotherapy.
