Mini pill/period question

Kaitlin

I'm 11 weeks PP- exclusively pumping. I started the mini pill last Tuesday. This Monday (6 days after starting pill) I started with brown gooey discharge and some cramping. Today I had bright red(like period) blood when I wiped. That was just 1 time. Now it's light brown again. So my question is- is this considered a period or spotting due to starting mini pill? I'm confused. Thanks!!!!
