Frustrated

So I had spotting, lasted only the morning at 11 dpo. Nothing since. I'vebe been getting cramps off and on. I keep thinking my period is gonna start. I so wish it would either just get here or I feel pregnant. Too bad the uterus can't just text me, "hey! Period's gonna be here this day." or " wohoo! Baby baking!" That would be awesome. I'm 12 dpo, if I calculated correctly. I think I'm due for my period Sunday?
