Current and past pregnant mamas!

My period is do today and I have no sign of her. The last two days I had intense period cramping to the point where I put on a tampon because I thought AF was coming. I have slight cramps today, literally almost nothing. This is not common for me. I cramp only one day and that is the day of my period. Has anyone experienced this and received a BFP? I haven’t tested as I’m scared to get a negative. I was thinking of waiting until Sunday which would put me at two days late. Please help. Maybe implantation is what i felt? I’m praying AF doesn’t show!
