You’re probably already aware that your body will go through many changes during pregnancy. But did you know that your breasts will experience the most dramatic changes?
You’ll notice the first signs of breast growth around the eight-week mark, and this enlargement will continue until your baby is born (and even beyond if you decide to breastfeeding). Your nipples will also grow in size and darken in color as they prepare for lactation.
Breasts grow up to one cup size
When most women think of pregnancy changes, they’re probably focused on the baby’s growth and how it compares to different fruits and vegetables (“He’s the size of a kiwi!”). But the breasts also go through big changes, as many moms-to-be discover.
Breasts may begin to feel sore or heavy during the first trimester, due to increasing levels of hormones oestrogen and progesterone. These hormones encourage the milk ducts and glandular tissue in the breast to grow. This can lead to breast growth, which can cause the nipples to become sensitive and painful. It’s not uncommon for women to go up a cup size during this time.
The nipples may also start to leak a straw-colored fluid called colostrum. This is normal, and you can use a bra pad to keep this liquid from getting on your clothing. It’s also not uncommon for the nipples to darken, and they may become more erect. This is all preparation for breastfeeding, which will begin in the second trimester. The nipples can also develop Montgomery tubercles, small, painless bumps that have antiseptic and lubricating properties, which will help when it comes to nursing.
They stay the same
When it comes to pregnancy, most women think about the baby’s size in comparison to fruits and vegetables (he’s the size of a peach right now). But your body goes through a lot of changes throughout this time as well, including your breasts.
Your nipples will change shape and grow in size as your hormone levels increase. This is due to a shift in mammary tissue and milk ducts, which can make your breasts feel sensitive and tender. You may also notice that your areolas become more pronounced and may look darker.
During the second and third trimester, your breasts will likely get even bigger as the glandular tissue grows to prepare for breastfeeding. They’ll also become fuller as they retain fluid. You may also notice that your nipples get more prominent with each passing month, and you might start to see veins on your breasts.
However, not all women experience these same types of breast changes. And that’s okay, too! Breast changes during pregnancy, breastfeeding and weaning are dependent on a variety of factors, including genetics, weight gain, and hormonal fluctuations.
They grow up to two cup sizes
From feeling like you’re going to burst out of your bras to watching the areolae take over more space on your breasts, many women experience dramatic changes in their boobs during pregnancy. But the reason for this change isn’t vanity-related: It’s because the hormones estrogen and progesterone stimulate the glands in your nipples to grow larger in preparation for milk production.
As you approach the third trimester, your nipples may begin to leak a straw-colored fluid called colostrum. Some women also notice that their nipples darken as the lining of their nipples becomes darker from increased blood flow.
As for the size of your boobs, most women go up a cup size during pregnancy. However, the amount of growth varies widely from woman to woman. In fact, some women don’t even notice an increase in their boobs during pregnancy. Regardless, this change is totally normal and doesn’t necessarily indicate your milk supply or whether you’ll be able to breastfeed. But don’t be alarmed if your boobs get larger or become sore; these changes are normal, too.
They grow up to three cup sizes
Women often start to notice breast growth around weeks 6-8 and it’s normal to go up a cup size or two throughout pregnancy, especially if this is your first pregnancy. The enlargement can also make the areolae feel tender and sensitive to touch.
Breast sensitivity is another common early sign of pregnancy, as the mammary glands prepare to produce milk for the baby. It’s not unusual for small amounts of straw-colored fluid to leak from the nipples, which can leave behind marks on your clothes. Using breast pads can help keep them clean and dry.
Some women don’t experience any breast changes, and that’s perfectly normal too. Even for those who do, it’s important to wear a supportive bra and exercise regularly, which can help keep the breasts firm and prevent sagging after baby is born. In addition, breastfeeding frequently can reduce nipple and breast tissue loss. Women who experience a discrepancy between the sizes of their breasts can also consider breast augmentation after the baby is born. However, it’s important to remember that cosmetic surgeries aren’t always a good option for every woman.
They grow up to four cup sizes
Pregnancy brings with it a lot of interesting body changes, including growth in the breasts and nipples. This can be uncomfortable and sometimes even painful. This is because pregnancy hormones — especially estrogen and progesterone — cause the breasts to grow and get fuller in preparation for lactation. This means that the nipples can also become more sensitive and may leak.
The first trimester is when the most growth happens in a woman’s boobs, but it can still happen during the remainder of the pregnancy as well. During this time, the nipples can become more pronounced and the areolas can change in color and size. This is due to an increase in blood flow.
Women can go up up to four cup sizes during pregnancy. This growth is caused by the rising levels of hormones oestrogen and progesterone, which trigger changes in the milk ducts and glands (called lobules) in the breast tissue. This growth can result in the nipples feeling more enlarged and heavier, which is why some pregnant women feel sore or even pain in their nipples.
