You have not given much information, but if you have taken a test at least 21 days after your last intercourse, then the test should be reliable. If you want more help, then please answer:
- What date did your last period start?
- What date were you expecting your period to start. I assume 12 September.
- How long is your cycle (typically 28 days)?
- What dates have you had sex since your last period?
