For those new to the thread, my girlfriend and I had sex at 3 am on wednesday. My girlfriend was on birth control but had forgotten to take her pill that day. So on thursday she got the morning after pill and began the treatment at about 4 pm. Now, about a week and a half later, she is almost 2 days late for her period. She took a first response test the day before her expected period and it was negative. Is the delayed period a result of the morning after pills? Or is there still a chance she is pregnent? Can we rely on this test? Am I just freaking out? Thanks alot everyone.
