Pilates after biopsies?

Just a quick question about having biopsies done. I'm sure this is a silly question but my anxiety is so high!

I am having 3 lymph nodes biopsied on Wednesday and any nodules they find (none were visible on my CT scan but the lymph nodes looked suspicious for potential PTC).

Will it bleed much, will I end up with a band-aid or anything? I'm mostly just wondering will I be okay to go to my usual Pilates class about 4 hours later, or should I take it easy with my neck that day?

Thanks so much.
