Fibroids During Pregnancy: Causes, Risks, and a Calm, Step-by-Step Plan

Nov 07, 2025

Fibroids are benign muscle growths in the uterus. Many pregnancies continue normally. Risk depends on size, number, and location. Typical issues are pain from degeneration, pressure symptoms, a low-lying placenta, baby’s position changes, and heavier bleeding at birth. Care focuses on pain control that’s safe in pregnancy, hydration and rest, targeted ultrasounds, and a delivery plan if a fibroid sits near the cervix. Surgery is rarely needed during pregnancy and is usually planned after birth.

What’s next: Below are the definitions, monitoring plan, pain options, delivery decisions, and when surgery is considered.

Understand the map: size and location guide decisions

Think of fibroids by where they sit. That tells you what to watch and when to adjust plans.

· Submucosal (push into the cavity): can irritate the lining and sometimes affect bleeding; in pregnancy they’re less common to discover first time.

· Intramural (in the wall): may enlarge early, then stabilize; large ones can press on the placenta or change the baby’s lie.

· Subserosal (on the outer surface): mostly cause pressure or, if on a stalk, rare torsion pain.


A single small fibroid away from the cervix is usually observation only. Multiple or large fibroids call for closer review.

“Fibroids pregnancy” monitoring: what your scans will look for

Follow a steady rhythm so small changes are caught early, not late.

· Dating and anatomy scans: confirm where the fibroid is relative to the cervix and placenta.

· Growth scans later on: check baby’s growth and room to move; revisit fibroid size if pain flares.

· Cervical assessment when needed: if a fibroid lies low, your doctor looks for possible obstruction to labor.

· Documentation you’ll see: measurements in centimeters, a diagram in the report (fundus/front/back), and notes on placenta distance from the cervix.

Pain and day-to-day symptoms: safe ways to cope

Most pain is from “degeneration” when a fibroid outgrows its blood supply. The aim is relief without risking the pregnancy.

· Rest, fluids, gentle heat on the lower abdomen for spells of cramping.

· Acetaminophen/paracetamol is the first-line pain medicine in pregnancy.

· Avoid NSAIDs late in pregnancy unless your obstetrician prescribes a short, supervised course earlier on.

· Treat constipation and cough so straining doesn’t worsen discomfort (fiber, fluids, doctor-approved stool softener).

Call the same day for severe pain, fever, persistent vomiting, bleeding, or new hard contractions.

Delivery planning: how decisions are made (no surprises at 38 weeks)

Your team links the last scan to the mode and place of birth.

· Vaginal birth is usual if no fibroid blocks the cervix and the baby’s head can engage.

· Cesarean is planned if a fibroid obstructs the outlet, if the baby cannot turn to head-down, or if the placenta is low with bleeding risk.

· Third-stage care: fibroids can increase postpartum bleeding, so hospitals prepare active management, uterotonics, and IV access ahead of time.

· Anesthesia planning: your latest hemoglobin and platelets are reviewed; epidural options are discussed early if you wish.

When is fibroid removal surgery considered?

Surgery during pregnancy is uncommon. It’s reserved for rare emergencies such as a twisted, stalked fibroid that doesn’t settle or a rapidly growing mass with red flags.
Most removals (myomectomy) are timed before a future pregnancy or after you deliver—once bleeding risk is lower and imaging is clearer. Your gynecologist will match the approach (hysteroscopic, laparoscopic, or open) to size, number, and location, and to your future fertility plans. If heavy periods or pressure persist after childbirth, this discussion moves up the list.

What you can do this week to stay comfortable and prepared

Keep a small routine that supports the plan your doctors set.

· Save your scan reports and bring them to every visit.

· Drink water regularly; short walks help with pressure and sleep.

· Use a belly support band if your back aches.

· Note baby’s usual movement pattern; a clear reduction warrants a same-day call.

· Pack delivery notes early if a fibroid is near the cervix so the team at triage sees the plan instantly.

Conclusion:

Most fibroids in pregnancy need structured monitoring and smart delivery planning, not urgent procedures. When you understand size, number, and location, you can see why pain settles with simple measures, why extra scans matter, and exactly when doctors consider fibroidremoval surgery—usually after birth or before another pregnancy. BirthRightby Rainbow Hospitals coordinates imaging, high-risk reviews, and anesthesia and delivery planning so you and your baby move through pregnancy with calm, informed steps.
