Cycle Day 45

I am on cycle day 45 as of today. The last period I had was On August 30th. I've been bloating constantly and feeling constipated for weeks now. I get dizzy every now and again, and there's certain smells I can't take anymore. The nausea is getting to me, but I don't feel pregnant. There's only a few days where my breast are really sore.. but the soreness eventually goes away. I'm almost two weeks late, should I test or go ahead and wait for my period? 
I wasn't trying to get pregnant, but I've always wanted a little one.. I just feel like my head is playing tricks on me and making me think I have symptoms. My SO said he isn't ready but would like to be a dad someday. Either way, he doesn't want me leaving if I am. Help?
