late period, but I've had all the symptoms

Lala
Okay, ladies, 
I'm 6 days late for my period, I know that's not long and it could possibly just be delayed. But, the day before my period was due I had a horrible pain throughout the whole of my stomach to the point I was doubled over all night massaging my stomach thinking my insides were about to come out of me.
The last 6 days that I should have been on my period was literally like I was on my period, but without the blood, the usual mood swings, the pain in both my but cheeks, the sore lower stomach, the constant need to pee. But still sign of the actual period. 
I'm giving my body an extra week to let my period make an appearance before I do a test. However I was just wondering your thoughts on this? has anybody experienced this before?
Thankyou
