Hi and welcome 
Mine are very wide too, maybe even moreso since I started this. Mine also feel flat against my ribs. Good thing for us though,even though taking pics it hard to see a change because they are soo wide when we take pics wearing a bra the more we grow the more its evident when we wear bras that push them together. Our cleavage will get bigger and bigger. I wouldn't have believed I'd grown at all if I had relied on plain old photos and not taken "bra comparison pics". Do take photos though, but bear in mind for SOME of us we cannot see change ourselves, where as others may
Ps don't get hung up on measurements. Your boobs can round out and fill out in places which the tape measure may/will never pick up on.
Look forward to your updates
