My period is 2 weeks late... I look plan b but still 2 weeks is really late. I took a test and it’s negative, should I go to the doctor and have a test done there too? The earliest I could get an appointment is 9 days from now so I figured I might as well book it and if I get my period before the appt I’ll just cancel it???

Advice or opinions on this???

I know plan b makes your period come late, but the pamphlet said my period should come within a week of my scheduled period or within 3 weeks of taking the test, well I took the test over 4 weeks ago
