How Much Upsize Should Your Bra Be In Third Trimester? Your Complete Guide
During the third trimester of pregnancy, many women experience significant changes in their breast size as their body prepares for breastfeeding. Some might wonder, how much upsize should your bra be in third trimester?
Understanding these changes and knowing how to adapt your wardrobe can help you stay comfortable during this special time.
Breast Changes During Late Pregnancy
Most women can expect their breasts to increase by 1-2 cup sizes during the third trimester, though this can vary significantly from person to person. For example, someone who typically wears a 34B might need to transition to a 34C or 34D.
The band size may also increase by 2-4 inches to accommodate your expanding rib cage. These changes occur due to increased blood flow, growing milk ducts, and hormonal changes that prepare your body for nursing.
Why Does This Happen?
Your body is going through an amazing transformation to prepare for feeding your little one. The breast tissue expands as milk-producing cells multiply and mature.
Additionally, increased levels of estrogen and progesterone cause fluid retention and tissue growth. This natural process ensures your body will be ready to nourish your baby after birth.
When to Shop for New Bras?
Around week 28-32 is typically the best time to reassess your bra size. Look for these signs that indicate you need a new size:
- The cup is spilling over or creating a “double bump” effect
- The band rides up in the back
- You notice red marks or indentations when you remove your bra
- The underwire digs into your sides or breast tissue
Choosing the Right Bra
Select bras with:
- Soft, stretchy fabric that can accommodate further growth
- Wide, padded straps to distribute weight
- Multiple hook-and-eye closures for adjustability
- A supportive but not constrictive band
- Cotton lining to prevent skin irritation
Detailed Timeline of Breast Changes
First and Second Trimester Changes
Even before your baby bump becomes noticeable, your breasts transform significantly. Tenderness and initial growth often start as early as weeks 4 to 6.
By the time you reach the second trimester, these changes become more apparent, with many women experiencing an increase of at least one cup size.
This growth is driven by the development of milk ducts and increased blood flow, both of which prepare your body for breastfeeding.
Third Trimester Specifics
The third trimester, spanning weeks 28 to 40, typically brings the most dramatic breast changes. Between weeks 28 and 32, most women find they need to increase their bra size by one to two cup sizes.
As your rib cage expands in weeks 32 to 36, adjustments to the band size become necessary. Finally, in the weeks leading to delivery, milk production preparation often results in another increase in cup size, making a properly fitting bra essential for comfort and support.
Band Size Changes
During pregnancy, your rib cage naturally expands by two to four inches to accommodate increased lung capacity. To find the right band size, measure directly under your breasts while standing straight.
Once you have the measurement, add four inches to determine your band size. If the result is odd, round up to the next even number for the most comfortable fit.
Cup Size Measurements
Accurate cup size measurement is crucial during this time of rapid change. Start by measuring around the fullest part of your breasts, ensuring the tape is level and snug but not tight. Subtract the band size from this measurement to calculate the difference.
Each inch represents one cup size: for example, a one-inch difference corresponds to an A cup, two inches to a B cup, and so on.
Detailed Bra Shopping Guide
Material Considerations
Choosing the right material is vital for comfort during pregnancy. Look for bras made from moisture-wicking fabrics to keep your skin dry and irritation-free.
Ensure they contain at least 15% spandex for flexibility and a cotton lining for softness against your skin. Seamless construction can help prevent chafing, providing an added layer of comfort.
Support Features
Proper support becomes increasingly important as your breasts grow. Opt for bras with wide shoulder straps, at least one inch in width, to distribute weight evenly.
Multi-way stretch panels in the cups and side slings offer additional support, while bras with at least three rows of hook-and-eye closures provide the adjustability needed for your changing shape.
Professional Fitting Tips
Frequent fittings are essential as your body evolves during pregnancy. Ideally, get measured every six to eight weeks.
When trying on bras, do so while seated and standing to ensure proper fit and support. The gore, or centerpiece, should lie flat against your sternum, and there should be no spillage of breast tissue from any direction.
Advanced Comfort Strategies
Day-to-Day Management
Maintaining a rotation of three to four well-fitting bras ensures their elasticity lasts longer. Hand washing your bras in cool water can help preserve their shape.
For leakage protection, use removable cotton pads, and don’t forget to adjust the straps weekly as your body continues to change.
Exercise and Movement
Physical activity calls for specialized support. High-impact sports bras with adjustable compression are ideal.
Look for styles with moisture-wicking properties to keep you dry during workouts, and consider front-closure options for ease of removal after exercise.
Nighttime Comfort
A sleep bra with light support can make a world of difference for nighttime. Wireless styles with soft seams minimize irritation, and crossover designs provide easy access if nursing becomes part of your routine.
Skin Care and Health
Preventing Discomfort
Caring for your skin is as important as finding the right bra. Apply unscented moisturizer daily to keep the skin hydrated and supple.
Gentle breast massage can improve circulation, while cool compresses help soothe tenderness. Practicing good posture can also alleviate strain on your back and shoulders.
Warning Signs to Watch For
While changes during pregnancy are normal, certain symptoms may require medical attention.
Sharp or shooting pain, unusual lumps or hardness, redness or warmth, and severe itching or rash should be promptly discussed with your healthcare provider.
Transitioning to Nursing
Preparation Timeline
Start preparing for nursing bras by week 32 of your pregnancy. By week 36, have at least two nursing bras ready, with one packed in your hospital bag by week 38.
Post-delivery, wait two to three weeks before purchasing more to account for size fluctuations.
Investment Strategy
Building a nursing bra wardrobe ensures you’re prepared for different scenarios. Invest in two to three structured day nursing bras, one to two sleep nursing bras, and one sports nursing bra.
Choosing bras with a slightly larger cup size can help accommodate milk production.
Long-term Considerations
Post-Pregnancy Changes
Your breasts will continue to change after delivery. Initial engorgement may temporarily increase your cup size, while size fluctuations are common during breastfeeding.
After weaning, your breasts may gradually return to a near pre-pregnancy size, though some permanent changes in shape and size are normal.
Maintaining Breast Health
Regular self-examination is important throughout this journey. Replace bras every three to four months during pregnancy to ensure optimal support.
Maintaining good posture, staying hydrated, and following a balanced diet contribute to breast health during and after pregnancy.
Commonly Asked Questions
Will my breasts return to their original size?
After pregnancy and breastfeeding, most women’s breasts will gradually return to close to their pre-pregnancy size, though some lasting changes in shape and size are normal.
Should I be concerned about rapid growth?
Steady breast growth during pregnancy is completely normal. However, consult your healthcare provider if you experience severe pain, redness, or unusual lumps.
When should I buy nursing bras?
Consider purchasing 2-3 nursing bras in the last month of pregnancy. Choose ones with some room for growth, as your breasts may increase another cup size when your milk comes in after delivery.
Caring for Growing Breasts
- Give your changing body the support it needs by:
- Performing regular breast self-checks
- Wearing properly fitted bras
- Moving and exercising gently
- Using pregnancy-safe lotions and oils
- Getting fitted by a professional if you’re unsure about sizing
So if you’re thinking about how much upsize should your bra be in third trimester, don’t think about it so much. Embrace these natural changes with confidence and comfort. This transformative time can be a positive experience with proper support and care, allowing you to focus on the exciting journey ahead.
Regular communication with your healthcare provider ensures any concerns are addressed promptly, allowing you to enjoy this special time with confidence and comfort.
