how fibroids affect fertility and pregnancy

Depending on where it is growing, it is possible for a fibroid to prevent or interfere with conception. In some cases a fibroid may stop a fertilised egg from implanting properly in the uterus. This is can result in an early miscarriage.

Women who successfully fall pregnant, despite having a fibroid, are more at risk of developing complications later in their pregnancy or during birth. Some of these complications include:

Bleeding : If the blood supply to the fibroid is obstructed during pregnancy, bleeding and pelvic pain can occur. Medical intervention is usually unnecessary as the bleeding tends to stop on its own.
Miscarriage: If blood flow to the placenta is reduced, a miscarriage can occur.

Odd position of baby: A very large or oddly shaped fibroid can force the baby into an awkward position, and a c-section delivery might be required.
Early delivery: Sometimes if the fibroid is very large, it will compete with the baby for space inside the uterus. This can result in an early delivery.

Obstructed labour: Fibroids that are near the cervix or those that grow into the birth canal can prevent a natural delivery and may result in a c-section.
Postpartum haemorrhage: A very large fibroid may increase the risk of abnormal blood loss during delivery.
