Unfortunately, during pregnancy, it is more difficult to accomplish because of all the changes your breasts are going through. Your breasts are growing in size, are tender, and sometimes may even be lumpy. It is still important for you to examine your breasts during pregnancy every weeks. Very common lumps found among women during pregnancy are clogged milk ducts. These are red, tender-to-the-touch, hard lumps in your breasts. Warm compresses running warm water over your breasts in the shower or applying a warm washcloth and massages will probably clear the duct in a few days.
If you are unsure of any new lump, tell your doctor on your next visit. Keep in mind breast cancer is rare among women younger than If you are planning on having a baby and are over the age of 35 , you may want to consider asking your doctor about a mammogram before you get pregnant.

What happens to my breasts during pregnancy If you think your breasts finished growing when you were a teenager, think again! Share this content. How breasts develop during puberty Your breasts are constantly changing from puberty to menopause. As you experience all of the physiological changes preceding the birth of your baby, which ones are preparing your body to breastfeed?
And how does the process work? You probably noted early in your pregnancy —at around the fifth or sixth week—that your breasts had become fuller and your nipples were more tender than before. Starting about the third month of pregnancy, the complex interplay of a number of hormones—including prolactin, estrogen, progesterone, and human growth hormone—leads to the proliferation of milk ducts and gland-producing cells in your breasts as your body prepares for milk production.
As your pregnancy progresses, the glandular tissue necessary to produce milk replaces much of the fatty and supportive tissue that normally makes up most of the volume of your breast. This causes your breasts to become substantially larger during pregnancy and lactation.
Such changes may worry you that breastfeeding will cause your breasts to sag or change shape after weaning , but there is no reason for concern. Once your baby is weaned from the breast when you stop nursing and your milk glands are once again replaced by fatty and supportive tissue and you return to your prepregnancy weight, your breasts will return to their approximate prepregnancy size and shape.
By the end of the second trimester, your body has become fully capable of producing breastmilk—which means that even if your child is born prematurely, you will be able to produce breastmilk. Colostrum , the first milk produced, is thick, somewhat sticky, and yellow or orange in color. If you notice yellow or orange stains on the inside of your maternity bra , your breasts are making colostrum.
However, some mothers do not notice any colostrum being secreted until after their babies are born. After your baby is born, the areolae of your breasts, and especially the nipples, will become exquisitely sensitive to touch. Oxytocin causes tiny muscle cells within the breasts to contract, squeezing milk from the milk-producing cells down the milk ducts toward small sacs or sinuses near the nipples.
