The structure of mammary glands is the following: there are from 15 to 20 alveoli inside of which there are lobules and milk ducts. Since there occur certain hormonal changes, the ducts and the lobules get bigger, more and more cells that are responsible for the production of milk grow.

In some cases, the weight of each mammary gland may get up to 600-700 g due to these changes. Therefore, the size of your breast gets bigger while you’re pregnant.

Breast Size in the First Weeks of Pregnancy

Most often, the size of your breast gets bigger during the first 10-12 weeks of pregnancy and the last weeks before labour. During the course of pregnancy, your breast may become several sizes bigger.

Apart from becoming bigger, your breast also turns out to be more sensitive. The changes that occur inside your breast result in it being more sensitive. Remember that you may feel discomfort even if you carefully touch your breast. In some cases, you may even feel a strong pain.

Many women experience these painful sensations during pregnancy. It’s fine. In case the painful sensations do not disappear after the 12th week, they will become less intensive. At the same time, you need to take into account the fact that this may not happen. Some pregnant women experience a strong feeling of discomfort during all the course of pregnancy.

Such changes as your breast becoming too much sensitive, swelling of your breast and it being painful to touch are one of the first signs proving that you’re pregnant. However, these are not the only changes that occur in your breast during breastfeeding.

During pregnancy, there may also appear a venous “spiderweb”. It occurs because the blood circulation is increased. The hormonal changes that occur in your  organism lead not only to the size of your breast being bigger, but also to the areolas being darker. As for the nipples, they swell and become puffy.

Besides, the process of colostrum production also occurs exactly during pregnancy. Colostrum is a forerunner of milk. The peculiarities of colostrum include not only its particular yellow color, but also a particular aroma emitted from your breast. You shouldn’t worry if, during pregnancy, you notice yellow liquid dripping out of your breast. It happens with all pregnant women and is in no way a sign of future problems you’ll face when breastfeeding. In some cases, the amount of colostrum dripping out of your breast may be quite big. That’s why you’re recommended to use special inserts that you put inside your bra.

The changes mentioned above are considered to be standard. These are common changes that occur during pregnancy. You shouldn’t worry if you notice any of them. If you notice any other changes apart from those mentioned, you should know that they might occur due to failures in hormonal background. In such like cases, there is a necessity to consult your doctor.
