Lack of PMS symptoms

So my period is supposed to start on the 23rd. Usually about a week and a half before my period comes, my PMS symptoms arrive. I get really sore breasts, headaches, and cramps in my stomach. I can't remember it ever not happening that way. I'm 10 dpo and am scared to test. I know sometimes the lack of PMS symptoms could be signs of pregnancy. Has anyone had no usual PMS signs, only to turn up pregnant? I've read stories on other sites about it happening. I just need actual advice! I'm super nervous and I really want this to be our month. We've been ttc for almost 6 months and it's exhausting. I just want to finally see that little plus sign...
