Possible Battery Bulge 2015 Macbook Pro

Hello, I am in desperate need of some advice. I noticed that my Macbook Pro isn't sitting completely flush and wobbles a little bit. I immediately suspected that the battery is expanding and causing a bulge as this had happened before with my previous macbook pro. Everything still works fine and it is not that noticeable but I am concerned. Right now during the lockdown there are no apple stores open and I have editing work to do with deadlines over the next few weeks. Do I need to send it in for repair immediately or is it safe to use while plugged into the an outlet. This is not one of the serial numbers associated with the recall, if that makes any difference. I'd appreciate any advice. Thanks!
