Did I skip a period?

A little background, I was on Depo for 7 years and Nexplanon for 3, my implant expired in April of this year, and I had it removed on May 12. I didn’t get AF until August 3rd. My period hasn’t returned but my temps suggest I should have had AF on September 10th. I think I skipped a period, can anyone give me any insight. Is this normal? Should I contact my dr?
