Could it be connected?

They’re both big and tender and they’re taking forever to go away. The one on the left went away once and then came back and it hurts because it’s right up against the bone. I get lumps like that pretty often but they go away. Then I’m spotting (which isn’t normal for me at all) and my periods have been pretty regular. Maybe it’s because I’m stressing about it? I know I’m not pregnant.
