LATE PD 10/16

Tr
My period was due yesterday I had faint yellow discharge. This morning and nothing! I've been ttc for about 5 years now and am getting a little nervous is my period coming or not? I have been experiencing minor pelvic cramps and heavily sore breast (sides, nips) I am about 17DPO  at about 9DPO I have been having horrid pregnancy dreams until last night where I dreamt about getting a BFP. Could this be all in my head? Fact is my period is late ,I have been experiencing weird non period symptoms , have tested about three times during my tww yesterday being the last day. Should I wait to test again?  I am a ball of nervous anxious mess!
