I do not think your are flat chested at all.   Maybe small breasted but I would agree with Lucy that mediums might be too small for you or you will outgrow them almost immediately.  Your breasts are cute and perky and very nicely shaped IMHO

Hiii. Hw r u doing? 
Bought large system as per NB advise. I started it yesterday. I don't understand y, bt after pumping my breast look elevated inside rather than being straight in the dome. And dome sits on the rib cage and I feel pain in the bone under n above the breast. M I doing anything wrong? Attached the image

How much do I need to pump? Until I fill it? Or would it going to happen in coming days?
