Waiting... Pregnant or late period?

Tiffany

Ok guys, so I had a D and C Dec 6th, a period Jan 2-9, I’m due for my period again tomorrow, however normally I have severe cramping days leading up to AF, and back pain. Granted, I’ve had some “light cramping” but nothing severe, song with very tender breasts. I always start way before the app tells me I’m going to. I’ve taken a pregnancy test and it was negative. What could be happening? Is it Too early to tell if I’m pregnant?
