3 miscarriages. fetal karyotyping normal. d&c revealed uterine septum, but have healthy 7 y/0. what tests should i/we have next? $ is an issue.

Depends on you: To some extent you already have a good deal of information.You know that you can carry a baby to a healthy delivery. You also know you have a structural uterine defect that may cause a miscarriage. I'm not aware if they could reduce or remove your septum, or if such surgery would help.That may be a reasonable thing to discuss with your doc.
