Pregnant?

I have been trying for a very long time...years... and lately I find myself looking for signs of pregnancy before my period which makes it late from stressing. Normally my signs are things that can occur to anyone, like weight gain or late period. This month seems different but I'm afraid that I'm just getting my hopes up and have myself convinced it again. I have sore boobs the last 2 days, a metal taste in my mouth, I spotted once while peeing (2 weeks after period) and I just realized that maybe my almost fainting spell while shopping could be nauseousness... I also had a bad pain in my side for a full day which I thought could be another cyst bursting(had that in the past). I however don't feel tired or ill. Afraid I'm turning into one of those people who convince themselves they're pregnant with all signs showing on body....
