Scared of MC

This is my 3rd time being pregnant. My first 2 ended in MC at 6 weeks and 7 weeks. Both times I noticed brown flecks in my discharge which eventually progressed to spotting and bleeding. I got a doomed feeling each time and knew something wasn't right. Today I'm 5 weeks 5 days and I noticed a couple brown flecks and am feeling VERY hesitant. Anyone else experience this? Am I overreacting??
