Two days before EDD, yesterday I noticed that my breasts swelled up, became sensitive and painful, like in the first trimester. I still haven't had any colostrum, but with my first son it was also like this, the colostrum didn't leak, but after giving birth everything came back and I fed for a long time. But there were no pains in my chest in the last weeks of pregnancy. Girls, who had breast pain in the last weeks? Is it related to approaching childbirth?
