Abdominal ache, period in 8 days...?

Chelle
I never cramp until a couple says before my period, 8 more days until my period, and I'm having lower back pain, and feels like I'm about to start my period, but not as bad as it usually is.. Implantation cramps? I've done some research. Me and my hubby have been trying for 9 months... I've learned to not get my hopes up. Advice, please!!
