Introduction
Breast tenderness and swelling may begin between 4 to 14 weeks of pregnancy, although some women may not experience any breast discomfort throughout the entire pregnancy. When the gestational sac develops rapidly, high levels of estrogen and progesterone in the body stimulate the breasts, leading to mammary duct proliferation and causing breast pain and swelling starting around week 4 of pregnancy. If the gestational sac develops more slowly, breast swelling may start after week 9, or may not occur at all during pregnancy.
Generally, breast tenderness begins between 4 to 14 weeks of pregnancy, although some women may not experience it at all throughout the entire pregnancy. The timing of breast tenderness varies depending on individual physical conditions. Specific explanations are as follows:
After conception, increased levels of estrogen and progesterone in the body can trigger early pregnancy symptoms such as dizziness, fatigue, breast tenderness, reduced appetite, aversion to oily foods, nausea, and other related reactions. If the gestational sac develops rapidly, resulting in relatively higher levels of estrogen and progesterone, these hormones may stimulate the breasts, causing mammary duct hyperplasia and leading to breast pain or tenderness starting around 4 weeks of pregnancy. However, if the gestational sac develops more slowly, breast tenderness may not begin until after 9 weeks of pregnancy, and some women may never experience breast tenderness during their entire pregnancy.
When breast tenderness occurs during pregnancy, symptoms can be relieved through appropriate warm compresses or massage.
