Help!

I am now 17dpo and 5 days late for my cycle. I’ve taken many test and they are all negative. Has anyone experienced this and ended up with a BFP? I have tracked my cycles for 2 years. Ive never been more than 1 day late. I went to the doctor and all she did was a urine test, that was also negative. No other labs tho. She wants me to wait 2 months and if I haven’t started, then do labs. I’m so upset and can’t wait for 2 months to find out what is going on. Any advice would be great!
