Of the symptoms of pregnancy that cause the most discomfort, breast tenderness is one of the most painful for some women. Their breasts are very sore and tender, and simple things like dressing and showering become a pain inducing experience. This is one of the first pregnancy symptoms that women notice, even when other more common symptoms show up.
When you are pregnant, your body produces more of the hormones progesterone and estrogen. This is to get your breast ready for breastfeeding your baby. Increased production of the estrogen and progesterone is required to prepare the breasts for nursing. The increase in hormones and the changes taking place in the breasts to prepare for the baby are the cause of the pain. A good nursing bra will help with support and comfort to alleviate some of the soreness.
