19 months post BA - shrinking and rippling :(

Hellooooo ladies! Long, long, long time no see! I hope you are all well, and are either enjoying your new boobies or getting ready to have a fab new figure!
I feel awful for just dropping in to pick your brains, but I have no idea who else to ask, so I'm hoping you guys don't mind me popping in to post a question.
For a general recap, I had my BA March 2011. I had very little breast tissue (30AA) and had 375cc extra high profile unders. Everything went well and I measured as a 30FF post BA - but they did look only around a DD. Fast forward 19 months and I am now 100% sure they are shrinking. For the past 2 months, I've only been able to wear a 32D - a DD which did fit me before (popping out but fab cleavage) is too baggy and there is no way I would be able to wear anything like an E cup. Has anyone ever heard of anything like this? I have not lost weight or had any hormonal changes at all.
I also have quite a lot of rippling if you feel the underside and if I look very closely I can see almost a ridge on the bottom of my right boobie - they do remain soft though.
I know it's probably one for my surgeon but I would love to hear any theories about this - have been worrying about ruptures / leaks?
Thanks girls in advance

You may not have lost weight but could you have lost fat?? Have you been working out?? It just seems a coincidence that you feel you have lost volume and u have rippling as both would happen if the amount of tissue covering the implants is reduced....

Hey Flowergirl long time no see babe, but always nice to see you back

Unless you've had weightloss there shouldn't be any reason for your boobs to 'shrink' hun. Even if you did have a rupture, the implant will hold its form....

You got me stumped lovely. Hopefully your surgeon can shed more light on this for you and please do let us know how you get on wont you. Xx
