Pregnant women are very likely to experience breast pain, which is one of the earliest signs of pregnancy. Symptoms like breast tenderness, sensitivity, and a stinging sensation usually appear within 3-4 weeks of pregnancy, sometimes even before a pregnancy test can be taken. This is primarily because, to better support the growth of the fetus, the body produces more estrogen, stimulating the growth of mammary glands and causing breast pain. Of course, as the pregnancy progresses and hormone levels gradually stabilize, breast pain will be alleviated. Pregnant women should not be overly concerned. However, it is also important to remind pregnant women that while this breast pain might increase discomfort during pregnancy, it is usually bearable. If the breast pain becomes unbearable, it is still essential to visit a hospital for a check-up.
