12 weeks and bleeding

Shelby

This is my second pregnancy ( first one ended In miscarriage at 10 week) I’m currently 12 weeks and I went to the restroom and I was spotting. It was quite a lot at first light red/ pink but after 30 minutes it stopped. Should I go to the emergency room? I have a doctors appointment tomorrow morning for lab work at my OB. Should I just bring it up then?
