Hello,

If you had an unprotected sex with your partner and she did not take the morning after pill within 72 hours of unprotected intercourse, nor is she on any contraceptive pills than she can be pregnant. The body takes time to develop the detectable amount of HCG levels. Pregnancy is usually not positive till the time of the missed period, pregnancy test gets positive 3-4 days after implantation, it may take longer.

You may not worry if she took the morning after pill within 72 hours of unprotected sex, but otherwise go for another pregnancy test, let it be done in a laboratory and make sure she collects the first midstream urine in the morning (after waking up) to be given for test. If you again get a negative test, you can consult a gynecologist and get an USG (Uterus) done.

Hope I have answered your query. Let me know if I can assist you further.
