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.
