A full-term pregnancy usually means completing 40 weeks. However, some babies may be born past the 41st week of pregnancy. It is not unusual for babies to be born before or after completing the full-term gestation since only around 5% of births occur on the due date (1).

In this post, we explain the physical changes you may experience and the baby’s development in the 41st week. This post also explains the signs of labor in the 41st week of gestation and some tips for moms and dads-to-be to follow before labor begins.

Stage of Pregnancy At 41 Weeks

At 41 weeks, you are nine months and one week pregnant.

Size Of The Baby At 41 Weeks

The baby is as big as a watermelon this week. Your baby is fully developed by this week and measures around 48-56cm in length and weighs around 3.2-4.1kg (2).

Read on to know how your baby is developing this week inside the womb.

When your delivery is overdue, the level of physical discomfort remains the same as before the 40th week. Some of the symptoms you will experience in the 41st week are discussed next.

Symptoms You Experience In The 41st Week

Here are the common symptoms a pregnant woman experiences in the 41st week:

  • Pelvic discomfort: The baby has moved down into the pelvis and starts putting pressure on the pelvic area, causing pain there. More urge to pee than before.
  • Hemorrhoids: The pressure of the baby’s weight on the rectal and pelvic nerves causes hemorrhoids, which can be painful.
  • Difficulty in sleeping: The bigger bump and the hormonal fluctuations may disturb your sleep. Using a pillow between the legs while sleeping can help.
  • Frequent urination: The pressure that the enlarged uterus applies to the bladder leads to frequent urination.
  • Contractions: It is common to experience abdominal tightening more frequently now, as the baby and the uterus are getting ready for delivery.
  • Diarrhea: It may be an indication of your nearing labor because the rectal and intestinal muscles become loose as you head towards labor.
  • Ease of breathing: As the baby moves down, the pressure on the diaphragm is released that makes breathing easy.

The physical changes in the body are the same as before. Read more about it next.

Bodily Changes In The 41st Week

The physical changes include (4):

  • Enlarged breasts: The breast grows in size as it prepares to lactate, to feed your newborn baby.
  • Colostrum leak: Some women can experience leaking of colostrum from the nipples. It is the first form of mother’s milk that your baby will have.
  • Blue veins: These are more prominent in the areas like the breast and thighs, as the blood flow will be greater towards these parts of the body.
  • Stretch marks: The stretch marks will be more prominent by this time as your tummy is fully expanded.
  • Cervical dilatation, effacement, bloody show
  • Fetal movement becomes less

The emotional changes include anxiety and mood swings

As your pregnancy is overdue, the doctor will check to know how soon you can get into labor.

Your OB/GYN Visit

The doctor will check for the following during your appointment this week (5).

  • Weight gain, blood pressure, and urine test for protein.
  • Recheck due date and dating scan for confirmation.
  • An ultrasound will be done to check the length and weight of your baby, and the abdominal circumference of the baby’s belly.
  • Check the position and size of your baby.
  • Check the cervix for vaginal dilation.
  • If the labor doesn’t start this week, then the doctor may suggest labor induction keeping in mind your health and your baby’s health. It is the time to induce labor as perinatal mortality is high after 41 weeks

If the labor begins this week, then it is necessary that you are aware of its signs. Read on to know about the labor signs you may experience.

Signs Of Labor In The 41st Week

Here are the signs of labor you must look out for in the 41st week of pregnancy (6):

  • Baby drops down deep into the pelvis, a phenomenon called lightening.
  • A constant water leak, which may indicate the rupture of the amniotic sac.
  • Frequent or painful contractions at regular intervals.
  • Discharge of a thick mucus plug indicates that labor is imminent.
  • Increase in the vaginal discharge, which can be slightly pink, or bloody in color. This is also called ‘show’.
  • Low, dull backache
  • Cramps with or without diarrhea

If labor doesn’t start on its own, then the doctor may wait for a few more days. In case of any medical emergency, labor will be induced.

Methods considered for labor induction are (5):

  • Stripping or sweeping: It involves stripping or sweeping the membranes surrounding the baby, which triggers the release of hormones that start contractions. It is a safe method to induce labor.
  • Rupturing the amniotic sac: The doctor uses a plastic hook to rupture the amniotic sac, which in turn stimulates contractions. It is done only after the cervix has dilated.
  • Ripening the cervix: It is done using a catheter-like instrument. One side of the tube with a balloon is inserted into the vagina and inflated. This causes the cervix to soften and open. This method can alone or in combination with medications like oxytocin can initiate contractions.
  • Administration of oxytocin: IV administration of oxytocin helps induce contractions, which start the labor within 30 minutes of medicine intake. Oxytocin is administered only after the water bag is broken.
  • Using prostaglandin gels: The gel is placed near the cervix to soften and open it, and to start the contractions.

The length of the time for the labor to start depends on how your body responds to the medication. After induction, the labor can start within hours or in two to three days.

Reaching the 41st week doesn’t mean that you can skip the healthy regimes. You must maintain a healthy diet and an active lifestyle.

Tips To Follow

The level of anxiety increases after 40 weeks in pregnancy. So try not to miss any prenatal visits during this week and next week since you are overdue. Here are some of the tips you can follow before labor begins:

  • Stay calm: Start packing your delivery bag. In the meantime, stay calm by practicing breathing exercises that can help you during delivery.
  • Spend time with your partner: Spend quality time with your partner. Discuss how you are going to share the responsibilities and how you want to deal with parenting ahead.
  • Do light exercises: Engage in light exercise to keep yourself active. This will also help in inducing labor. Make sure not to overindulge in exercises and stress yourself. Always consult the doctor before trying any new exercises.
  • Get good sleep: You must get enough sleep before you go into labor, since you may not get sufficient time to relax after the baby is born. Make use of the time to rest properly.

A woman can expect the best support from her partner during pregnancy. So, how can the husband help his wife during this week? Find out next.

Tips For The Dad-to-be

With your partner’s impending labor, you might feel anxious and jittery. Here are some tips that you can follow to ease your anxiety.

Check the insurance and related documents to avoid last minute rush and forgetting important papers at home.

  • Know your stuff: Understand what your partner is going through. Listen to the instructions given by your doctor. This will help you to act calmly and do the right thing when your partner’s water breaks.
  • Know what she wants: Understand your partner’s wishes while she goes into labor. Try to know how she wants to deliver or what method of induction would she prefer: through IV or the rupturing of the amniotic.
  • Know everything about hospitals: Enquire everything about the hospital, how they are going to address the patient, and what the hospital policies are.
  • Know when to take charge: at some point while in labor, your partner might not be able to take the right decision. If your partner is not able to make a decision, then step-in and talk to the doctor to choose what’s best for the mother and the baby.

Frequently Asked Questions

1. What causes a baby to be overdue?

The exact cause of a baby being overdue is not known. Sometimes, it may be related to heredity. It is also seen that if a woman had a baby after her due date in one pregnancy, she might have the same in future pregnancies, too (7). Some other causes of going overdue may include being obese, over 30, or pregnant for the first time (8).

2. Are babies born at 41 weeks healthier?

Full-term babies born between 39 and 40 weeks are healthy. Late-term babies born at 41 weeks are generally healthy but sometimes may experience complications, such as loose and peeling skin, overgrown nails, or creases on palms and soles (9).

3. How many days overdue can I go?

If everything is okay, your doctor may allow you to go overdue for up to two weeks. After two weeks, continuing the pregnancy may be risky for your baby’s health (5).

The 41st-week pregnancy might seem scary. The major concern during this period is that a fully developed baby has surpassed the time to enter the new world. In addition, the accompanying discomforts during this period may enhance your worries even more. However, this isn’t an uncommon situation. Hence, ensure to keep up-to-date with your appointments. Keep your Ob/Gyn informed and stay alert for any labor symptoms. The above techniques could help you stay calm while your uterus prepares itself for the delivery of your little one.
