LMP - 6 Feb 2023 .. my period cycle since last 5 months is of 30-31 days. I had unprotected sex (only for a minute) and no ejaculation occurred afterwards used a condom. This incident happened on 1st March and took unwanted 72 after a few days . My period was due on 8th of March but it did not come and i am 9 days late . I did a
pregnancy test today but it was negetive. What can be the reason of this delay?.. is there a chance of pregnancy?
