2nd Trimester Miscarriage?

Jennifer
Has anyone had any experience with recurrent second trimester miscarriages after  a healthy pregnancy, or even just second trimester miscarriage? I've done the research. I know what could be the cause. I just haven't met anyone who's experienced it twice and gone on to have a healthy pregnancy. Feeling defeated, but I do have an appointment with a specialist on May 6th. Lost my sweet little ones at 18/5 and 16/3 on New Years Day of 2014 and March 10, 2015.
