Hsg / recurrent miscarriage

Bre • Mom of 3👩‍👧‍👧👩🏽‍🍼06/01/21 , 05/22/22, 02/06/2024 Pregnant with #4 03/25 School Nurse& PRN icu nurse

Looking for anybody with info. I’ve had 3 back to back miscarriages . My doctor wants me to get a hsg test. But the only success stores I hear are about women who’ve had their tubes blocked and then were unblocked during the procedure . I get pregnant easily but sustaining the pregnancy is my problem . I’m not to sure what the hsg can do for me . Anybody experience this ?
