 You had a period after having sex and you have taken a home pregnancy test that says you are not pregnant.  Then you are not pregnant.
 
 If you have a period after sex you cannot be pregnant as you womb has been cleansed of everything that may have been in there and is preparing for the next ovulation cycle when you can get pregnant.
 
 Tension brought on by stress thinking you may be pregnant or work related stress is the biggest reason why women miss a period.  Other factors could be an illness even something as minor as a cold.  Medications such as over the counter cold remedies and antibiotics prescribed by doctors can disrupt your cycle as well.
 
 IF you miss more than one period then you need to see your GYN.  Otherwise based on what you have written I 99.99% sure you are not pregnant. If you wish to make really sure take another home pregnancy test to verify the results of the first test.
