A urine
pregnancy test only becomes reliable once your body has built up enough hCG hormone, which usually means testing after a missed period or about three weeks after intercourse. A clear negative done earlier than that can still turn positive later, so it doesn't fully rule things out on its own.
Next Steps
If your period doesn't start within the next few days, repeat the test with your first morning urine, or get a blood
beta hCG test for an earlier and more accurate answer.
Health Tips
Please see a gynaecologist if your period is more than a week late with a negative test, or if you notice pelvic pain or unusual bleeding.
