Is this normal?

So I finished my period about 10 days ago and it was like, really weirdly light? Like usually I’ll have a few days of heavy flow and then it slowly peters out but this time it was super light and mostly brown blood. And now over the past few days I’ve started spotting quite a bit, which definitely isn’t normal for me. I have a few ideas about what could be contributing to this, like my recent medication change(not bc) and an overall increase in stress. I’m also 17 and my periods have never been exactly regular, but I’ve never had something like this. Does anyone have any other thoughts on what might be going on? It’s mostly the spotting I’m worried about. I don’t wanna rush to the doctor if it’s just a temporary hormone imbalance thing due to meds, so any info and thoughts are very much appreciated☺️
