Am I pregnant already? 6 days delayed

Hi! I am 6 days delayed. Will be sharing a my PT's from Feb 17 up to today. It gets darker everyday and nagpabili ako ng diff brand ng PT sa 2nd photo. Medyo takot lang ako now kase I had a miscarriage last year 🥺 pero hoping na this is a sticky baby na and healthy baby 🙏🏻🙏🏻🙏🏻
