Breasts are hot - sore and itchy. Anyone else?

Jg • Pregnant with TWINS after mc in April 2015 -looking forward to this journey - trying my best not to be anxious
I am currently 18 weeks and 2 days pregnant with twins - my breasts have already grown quite a bit - the one Place I didn't put stretch mark cream and have some starting on my breasts in the under part (oh well) but I am finding they are hot and so itchy sometimes. Has anyone else experienced this? I don't mind the getting bigger part but oh man is it ever uncomfortable lol
