Bleeding at 10 weeks 5 days

Good Morning Ladies, has anyone experienced bleeding in the second half of their first trimester? I'm 10 weeks 5 days and having light pink/brown spotting. Waiting to hear from my doctor and freaking out. This is my first pregnancy and I have not has any spotting before today. Also have to lead a very important 4 hour small group meeting this afternoon and don't know what may happen with my body today. Any advice or tips would be sincerely appreciated.
