Risk of Miscarriage Based on Presence of Bleeding and Fetal Heart Rate
The risk of a miscarriage early in pregnancy depends on the age of the pregnancy, whether there is a bleeding or not and whether there is a fetal heart rate. With vaginal bleeding, the risk of miscarriage is high before you see the fetal heartbeat and low without bleeding after you see the heartbeat.
Risk of Miscarriage
| Pregnancy Weeks | Bleeding | No Bleeding |
| Under 6 weeks | 33% | 16% |
| 7 to 9 weeks | 10% | 5% |
| 9 - 11 weeks | 4% | 1-2% |
If you bleed before 6 weeks before you see the fetal heart rate your risk of miscarriage is about 1 in 3, and without bleeding, after 9 weeks the risk of miscarriage is very low.
