[|Human|] I had unprotected sex 12 days ago, I think I was supposed to get my period this morning and did not.  I am usually 28 days on the dot.  I also took Plan B within 72 hours of unprotected sex.  I took a pregnancy test this morning and it was negative.  Can I be pregnant and if so how likely is it?
[|AI|]  Hi, Thanks for asking. I understand your concern. Plan b contraceptive prevents pregnancy when taken within 74 hours of sex... earlier the consumption better are the results As you had taken the pills in 74 hours . You have the least chances of conception.  Pregnancy test of urine is reliable when done after 8 days delay in periods. If you want early reports you should go for blood pregnancy test (Chat Doctor test).or go for repeated urine test after 8 days delay in menstrual date.  Thanks.
