I need an honest opinion about this: am I be pregnant? URGENT?

Take a test 6 weeks after your last period. Unlike what most people believe, you don't get pregnant when you have sex. you don't actually get pregnant until 6-10 days after sex (if you have sex during ovulation which happens 10-14 days before your period). and normally it takes 1-2 weeks for anything to show up on a urine test after implantation.
