PP bleeding w the patch (posted in period talk as well)

I’m almost 7 weeks PP & I haven’t started my PP period yet. I started using the patch for the first time 2 weeks ago, (the first time I’ve used BC since having the baby) I just changed it out yesterday. I just went to the bathroom and there was blood, like spotting but a little bit more than that. My patch free week isn’t for another 2 weeks. I am confused? Why am I bleeding? Is my period starting or is this just spotting associated with the patch?
