Could it be?!

So my last period was 11-16 to 11-23 then my fertility started 11-30 I had sex from 11-30 to 12-4. I am now 35 days into my cycle and still no period I took a pregnancy test 12-12 and it came back negative. My normal cycles I have cramping a week before I start but so far only light sporadic cramps just on one or the other side of my uterus. I only had spotting on 12-1. My beasts have been very sore and grown quite a bit! I don't want to get my hopes up and get the blood test yet, but could my mind be tricking my body? I've never gone 35 cycles days without AF or atleast my normal cramps and crazy hunger pains. I'm taking another test in a week but the month is ending soon and don't know what else could be happening to my body. Any ideas or experiences?
