I'm 2 weeks post op and wondering if the "fluttering" feelings are normal?

It's really hard to describe these "fluttering" (for lack of a better word) that I get-sometimes it's just my right breast, sometimes both. For the female plastic surgeons who've been pregnant, it reminds me of when the baby first moves, albeit ever so gently. Sometimes it feels like the implants are moving. Is this all normal? What else can I expect? Thanks! (PS had 2 week check with PS yesterday and forgot to ask this- he did say I'm healing great)
