Sucking/gurgling Sound

[PTalk78]

Hey men, was just wondering if anyone is having the same experience. During my last few pumps getting up to 100% (and a little when first deflating), I get this new sound. Best I can describe it, is as a gurgling noise, like when the last of the water goes down ur shower drain. It's a sucking/gurgling noise; and I believe it happens as the pump RE-fills. Its just started maybe a month ago, and I'm about 3.5 years implanted as of now. My immediate thought was that I may have leaked some fluid but what do I know? I also cringe at the idea of the pump having an issue bc I do love the thing and get a helluva lotta use out of it. So if anyone has an insight, reply or msg me. Appreciated much. Thx to my bionic brothers for all the insight, dialogue, ideas, mentoring, etc.
