Brown flakey discharge

I'm now 11 days past transfer of 1 embryo. I had cramping the first 8 days after transfer and now I'm having a brown flakey discharge when I wipe. Anyone else experience this? Should I be concerend? I go Friday for blood work to see if I am Prego or not. Last round of <a href="">Iui</a> ended in double mc so I'm nervous :/
