Anyone else's boobs suddenly start reacting to the pregnancy in the 2nd trimester? With my previous pregnancies, it happened almost immediately after conception. I've had a boob job since my last preg tho, so when they didn't get sore and swollen in the first tri, I figured it was just because of the implants. But now I'm 16 weeks and suddenly they are huge and it hurts to even let the bra or shirt touch them. Anyone else develop this symptom randomly in mid pregnancy?
