PMS or Early Pregnancy??

Krystle
Last period Nov 9th. Ovulated approximately Nov 24 or 25 based upon cervical mucus and high sex drive. I have had tender breast since Nov 30, excessive belching and gas. No spotting but AF was supposed to start today (Dec 7), no sign of it yet. Tested Dec 3 morning & 6 evening (both were negative). Should I test again or wait a few days late.
