Chances of getting pregnant

Melody
Hello ladies: 
I hope to get some info from everyone; I had sex with my bf on October 11th unprotected, (no condom and no birth control) my period was late for a week I already took one prego test (clearblue digital) on Monday (October 27th) but if said I'm not prego. This morning (October 29th) I got my period. It was late 7-9 days. What do you think is my chance of still being prego?
