My boobs ached from day one of my last pregnancy. So much that it hurt to even give DH a hug. This time round, they've only just started changing at 15 weeks and are a teeny bit tender if they get squished (usually by DD's elbow!). This pregnancy has been SO different that it has me wondering if it's really happening. The growing pot-belly and HUGE appetite are a bit of a give-away though! All the best, I'm sure your little one is just fine in there.
