Me and my boyfriend had unpertected sex 11 days before my period is due . can i be pregnant or is it too early to know ?

To early to tell: It really is too early to tell by a pregnancy test if you are pregnant. Home pregnancy tests are generally 99% accurate.The most common problem with hpt kits is a negative result because the test was performed too soon after the expected onset of menses. If pregnancy is suspected despite a negative test, the test should be repeated in one week.
