Home pregnancy tests detect the hormone hCG in urine. Testing at the right time — and correctly — gives the most reliable answer and avoids confusing false results.
Test from the first day of a missed period (or ~3 weeks after unprotected sex)
Use the first urine of the morning (most concentrated)
Follow the timing on the instructions exactly
A faint line usually still means positive
Repeat in a few days if negative but your period has not come
When to see a doctor urgently
A positive test with severe pain or bleeding (possible ectopic — urgent)
Repeated negative tests but no period (see a doctor)
Confusing or unclear results
Too early can read falsely negative. Testing before your period is due can miss an early pregnancy. A blood test at a clinic can confirm earlier and more precisely. MedDroid gives general information, not a diagnosis.
Frequently asked questions
How soon can I take a pregnancy test?
Most home tests are reliable from the day your period is due. Some “early” tests claim a few days sooner, but testing too early can give a false negative.
Does a faint line mean pregnant?
Usually yes — even a faint line generally means hCG is present. Repeat in a couple of days to see it darken, or do a blood test to confirm.
Can a test be wrong?
False negatives happen if you test too early or with dilute urine. False positives are rarer but can follow certain medicines or a recent pregnancy loss.
