Hi, I was on the birth control pill for an extended period of time and just recently went off about to months ago. My last period was from July 12th-16th 2012. I was sexually active three times following that period. I was two days late on my next period, projected date august 2nd, when I had unprotected sex, august 4th. I then took the morning after pill within approximately 12 hours. It has been two days since then, approximately 5 days late on period and two days of morning after pill with no spotting or bleeding. When can I take a pregnancy test and how accurate will it be?
