Pregnant or Not?!?!

Laura • TTCING baby #3 since November 2011
Ok I am on cycle day 30 with my period due in 6 days. I had some spotting on day 24-25 and have had a whole slew of symptoms since, suck as nausea and itchy breasts. I don't know if my symptoms are real or imaginary because I want this so bad!! BDed last night and today I have EWCM that had a streak of blood in it. I am just so confused right now! So do you think I am pregnant or not? I am trying to hold off testing until Thursday or Friday after AF is due.
