I had d&c 2 months ago. i also have hashimoto's could this be the cause of blighted ovum?

If not recurring...: Having one blighted ovum doesn't lead to any current speculations nor to predictions about future pregnancies. Plenty of women have one blighted ovum during their lives. However, if a woman has several blighted ova, her doctor may look for a genetic cause or other reason for the recurrences. Occasional miscarriage is a normal part of human life, and one way that nature stops abnormal embryos.
