10 dpo and brown spotting in the am?

I o'd on nov 15th opk did the bd, this morning when I woke up i had brown spotting that when I wiped was there, now there is nothing. I'm expecting my period on nov. 30. I have been extremely tired and my have been looking veiny and im constantly hot/ cold. How long should I wait to take a preg test, I did on 8dpo and it was bfn. I had a m/c sept 22, waited a cycle and I"m praying for a sticky bean & for a bfp!!
