Heart failure after surgery?

     Good morning all, so, as some of you may know, I, 43f underwent tricuspid valve replacement surgery on 9/9/25, then had a permanent pacemaker surgery on 9/16/25. Everything seemed to be going well. Was discharged from hospital on 9/17/25. I am using my spirometer as told, and getting my steps in. Now, starting about 3 days ago, I started to notice my shortness of breath is getting really bad. It’s not improving, it’s actually getting worse. To the point where I’m winded just from leaning up in my recliner to reach for something. Walking down the stairs to the bathroom requires me to take breaks every 2 or 3 steps, and by the time I finally make it back upstairs to my recliner I am literally huffing and puffing. BAD. Like it takes me a good 2/3 mins to even catch my breath. I’ve also noticed some swelling in my feet too. Which leads me to think I may have swelling around my heart which isn’t good. Or even heart failure . I hope and pray that’s not the case, but now I’m worried. I have an appt today at 1:30 so I will definitely bring all this up then. But I’m wondering if I should even wait until then. Should I go into the ER now? Or am I just exaggerating???
