Almost 10 Days late, TTC, and keep getting negatives

I've been off birth control for a year but just recently started TTC at the beginning of August. I had my period in August, but have yet to have one this month. I keep getting BFNs. The longest my cycle has been is 34 days and I'm now at 43. Any advice or suggestions? I just want to know what's going on and hope I'm pregnant...
