Stop, whose breast is this?

Estrogen and progesterone continue to be naughty. You have probably noticed that your breasts are much larger than they were. By the 7th week, some women’s breasts increase by a full size! Cool, yeah? If they weren't so tender... But this, alas, is also a normal process, your breasts are training to produce milk. Also, look at your breasts carefully: most likely, your nipples and areolas have changed a little. At first they begin to bulge more than usual, then you’ll notice they darken and increase in size.
