What do you do if all of your tests are normal but still have recurrent miscarriages?

In a good amount of cases (about 60-70%) there really isn't an answer and all tests wind up being normal. If this is the case, sticking to the fight is always good, as the chances for a subsequent live birth is still 50-60%... A doc given his/her experience can also try different meds, such as Progesterone, baby ASA, etc, many things however, can be very controversial and expensive so make sure you do your research if other things are presented
