Help!!! TTC late period but still BFN

Samantha
My last period was the 6/1 lasted 5 days my cycles are 30-32 days usually and now I'm now on cycle day 43!! I tested on my AF due date with a BFN and tested a few days later with a BFN around the 9th! Should I test again? If I'm still getting a BFN should I ring my doctor? TIA X
