brown discharge !

Nor • I am 27 almost 28 , one year happily married , TTC for 4 months now *wish me luck*
Is a brown discharge a "spotting" ?
My period should be come in 7 nov 
And today I have brown discharge & my breast hurts I couldn't even wear my bra and they look bigger I was think "maybe it's just me" but my husband notice !
and my back is another story 😭
Should I take a test tomorrow ?
