Am I?

Savanna • Married November 29, 2013. TTC for 4 months.
I have had sore breast, mostly my nipples though. They have also been itchy or tingly, I'm not really sure how to describe the feeling. I also have been nauseous, had headaches, and have been extremely moody. I started having cramps 6-7 days ago and I am now 5 going on 6 days late for af. Should I hold off anymore or should I just test? I don't want to get my hopes up anymore so that's the only reason I haven't tested yet.
