Continue testing or consider it a missed period?

My period should have started around June 22.

I took an at-home test June 29 and June 30, both were negative. My doctor ordered a urine test so I went in for that July 2, which was also negative.

My doctor said continue on my birth control but I can’t help but think - why do I still not have a period?! I have never skipped a period before and am consistent every day with birth control.

Do I continue making myself crazy and testing a few times a week or trust the doctor and go back to life as usual?
