Lack of PMS symptoms = pregnancy??

Abby
Last month I had major pms symptoms, very sore breasts for like 2 weeks, and I thought I was pregnant, until I got my period. This month my boobs were sore during ovulation only and now they're not at all. Has anyone heard of lack of PMS symptoms indicating pregnancy? I'm reading mixed things about it online. Has anyone gotten pregnant and had zero pms/pregnancy signs before testing positive?
