Congrats babe they look gorgeous! Ur boobs will gradually drop a little more each day or so and fluff out ie get softer to the touch, move, feel bouncy and natural to the touch, you can feel them bounce when you walk/job etc.
Their appearance and feel will be more natural and u will eventually be able to squish them together and they’ll fit into a bra cup. This happened from wk 3/4 onwards for me. The change is ever so slightly but week by week u notice loads. Fxxx
