Decidual Cast vs Blood Clot Images
Many people confuse a decidual cast with a large menstrual blood clot — but they are very different.

|---|---|---|

| Texture | Firm, tissue-like | Jelly-like |
| Integrity | Comes out in one piece | Breaks apart |

This is one of the biggest concerns.
A decidual cast can look similar to miscarriage tissue, but they are NOT the same.
Key Differences:
- Miscarriage often includes:
- Pregnancy tissue
- Severe cramping
- Ongoing bleeding
- Decidual cast:
- Usually a one-time event
- No pregnancy tissue
