Has anyone had any spotting that the doctor actually needed to do something about?

I’m 7 weeks 2 days and my 8 week dating ultrasound is next week on Monday. I started spotting pink to brown Saturday night that kinda went away but now is still there a tiny bit. I’m not super concerned about it and neither is my doctor but they did give me the option of coming in, the only problem is I’d still have to come back on Monday they can’t move my dating ultrasound up. Did any of you have any issues related to spotting that they actually could do anything about? If so I don’t want to be making a dumb decision by not going in and potentially needing intervention for something, but I also don’t want to go in for no reason.
