Palpable uterine artery pulsation

La
Heard that PUAP can be a sign of very early pregnancy. See below medical study findings.

If I am pregnant this time, if only be 3-4 weeks. Has anyone who has been pregnant before ever had this early in pregnancy and later confirmed to be pregnant?
This will be my first.
