Hi Sarah, your still very early post op, you will still have alot of changes to go through during the coming months but the stage your at now should be the final results in terms of where the implant sits and the pockets that were created for it so yes your breasts may get bigger/smaller, change shape, relax more creating a fuller looking bust etc…… but your gap should not continue to grown once you have reached this mark so hopefuly it wont, if it does i would reccomend taking pictures weekly/monthly to document the changes.
Also your issue at this point may just be that they have not softened enough yet to create a clevage in a bra (i was seriously nearly 5 months post op before mine even started to soften enough to do that) so dont loose hope yet, i know 3 months feels like forever when your waiting for them to evolve but you are still very early on in your journey, do you have a pre op you could share and any process pics?
