PMS vs. pregnancy?

I feel like one of the most difficult parts of the TTC journey is trying to distinguish pms symptoms from pregnancy. So I’m 8DPO my period is scheduled to be starting a week from now. Since 6DPO, I’ve had cramps( mostly on the left lower abdomen) back pain, burping extra, and feeling very hungry. Mild breast tenderness, and creamy CM

Anyone have anything similar and then found out you were pregnant 😭

Really praying this is our month 🙏🏻
