spotting at almost 10 weeks

Alex • Blessed to be mom to our miracle IUGR baby boy! I've never met someone as strong and brave as he is!
So I just started spotting at 9 weeks 5 days. Not a lot just when wiping, but it's red. Called my ob and the dr on call wasn't too concerned. Just said if it gets heavier or still happens on Monday to give them a call back. I just had a nightmare about miscarrying yesterday and now this. I'm terrified. Anyone have this and the baby was fine? What was the best way to calm yourself down?
