Have I ovulated late or is my body playing tricks

Amanda
So hey ladies iam on cd 42, 14days late for AF, with bfn's!! I have rang my doctors to get blood work done and can't get an appointment until 4th August. She said I could have ovulated and implanted late. Has anyone else been in the same situation. Just really want to no if I'm pregnant or not. I'm never late for my period and I just feel pregnant. Little frustrated. Thanks ladies
