Missed Period

Okay, so I don’t really know what to do. I had the nexplanon in my arm from June 2019- August 22, 2019 (yes, only 2 months, I hated it.) I had a period from August 24-27. I haven’t had one since. I am currently 24 days late. I took a test two weeks ago and nothing. I have been extremely irritable, tired and emotional. Should I test again? I’m trying to hold off on consulting my doctor and I know irregular cycles are normal coming off of birth control.
