After miscarrying several times & getting two abortians what are yout chances of being unfertile young?

Depends. Given a history of recurrent miscarriage, one's prognosis for a live birth depends on: - current age of woman - results of evaluation for recurrent pregnancy loss assuming woman is <40 years old and evaluation is normal, chance of live birth with next pregnancy is ~65-70%.
Low. It sounds like the issue may not be getting pregnant but getting to have a live birth. Some women who have multiple miscarriages have reasons that predispose them to another miscarriage. There are genetic, hormonal, anatomical and blood clotting reasons why that may happen and all can be evaluated by a specialist.
