Fibroids during pregnancy are quite common, and in most cases babies grow normally. Still, the effects can vary depending on the size, number, and location of the fibroids. Here’s a clear, balanced overview:
What are fibroids?
Fibroids are non-cancerous growths of the uterus made of muscle and tissue. Many people have them without symptoms.
Effects on baby’s growth
✅ Most of the time
Baby’s growth is normal
Fibroids do not usually affect the placenta or baby directly
Many pregnancies with fibroids go to full term with healthy babies
⚠️ When fibroids can affect growth
Growth issues are more likely if fibroids are:
Very large
Multiple
Located inside the uterine cavity or near the placenta
Possible effects include:
Restricted space in the uterus (rarely leading to slower growth)
Placental issues if a fibroid interferes with blood flow
Increased monitoring for fetal growth restriction (FGR) in higher-risk cases
Other pregnancy effects (not growth-related)
Fibroids may increase the chance of:
Pain (especially in the 2nd or 3rd trimester)
Preterm labor
Breech position (baby not head-down)
Cesarean delivery
How doctors monitor this
If fibroids are present, healthcare providers may:
Do extra ultrasounds to check baby’s growth
Monitor placental position and blood flow
Track symptoms like pain or contractions
When to seek medical advice urgently
During pregnancy, contact a healthcare provider if there is:
Severe or persistent abdominal pain
Vaginal bleeding
Regular contractions too early
Sudden decrease in baby’s movements (later in pregnancy)
