9 days late for my period

I’m 9 days late with only nausea, fatigue, moodiness, and extra emotional. I took a test yesterday and it was negative. I have never had a period come late like this and had these symptoms. I feel like I’m pregnant but the test said otherwise. I’m considered a high risk pregnancy too. I don’t know if I should wait another week and take a test or get in with my high risk OB and get a blood test in case my hcg levels are just low.
