Hi, i want ask what happened with my period. my last period was august 29th, i had sex on september, 14th. my husband cum outside. i have tested on september 28th, it shows one line, but my period still not showed?

Tests are accurate: For fertile women who are having sex... it can be hard to guess if a woman is pregnant, because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A home urine pregnancy test gives a accurate result by 3 weeks after sex (3 weeks after when conception might have occurred), 1 week after missing a period, or 1 week after starting a "weird" period.
