Sir i did sex a year before nd thn i had my regular periods for a year bt now my periods are delayed is there chance of pregnancy?

Not if: You did not have another sex since the previous year. If still concerned about pregnancy do a pregnancy test.

?question: As asked, it appears you had sex a year ago, and are now worried about being pregnant? If you had sex a year ago, and had a year of normal periods afterwards, you would not be pregnant. If you had unprotected sex recently, and your period has not arrived on time, then you may be pregnant.
