AF 2 days late...should I test?

Me
I am currently 2 days late for AF. (She should have reared her ugly face on Dec 7th)
AF always shows up between CD25-28(usually always showing up on CD28) 
I ovulated on November 24th and we had sex 23th,24th,&25th. I don't use OPK's or chart my temp, but this ovulation was different that all my others.... 
For the past 2-3 years I have only ovulated on my left side (I would cramp only on that side on the exact day ovulation is expected) well this time I actually cramped on my right side which caught me off guard. I mentioned it to my fiancé and he said "I wonder what that means?". 
Also, starting the day after I ovulate my breasts get tender and are very swollen up until AF shows then goes away. 
However, my breast did not start getting tender or swollen until 10DPO....Another thing that was odd that my fiancé pointed out BEFORE I realized my breast were swollen was that my veins were VERY prominent and I could almost feel them(that has never happened before). 
Starting on 12dpo I started getting on/off cramping and so I thought AF was about to show. I have continued to have on/off cramping since and now I'm 15DPO. I thought for sure that AF was going to show on Dec 7th because I was cramping and kept getting the feeling that I was "wet". 
Also, I kept having to use the bathrroom all day (and even in the middle of the night which I never do) yesterday because I had to pee but also because I had the feeling that AF showed and my underwear was covered in blood. But everytime I went, nothing!
I want to test but unsure if I should as I feel like it is too early and want to wait til after my expected AF has ended.
