1 week late but still a bfn..??

Kristen

so I am 6-7 days late ..i had spotting a week before I was due..the spotting lasted 3-5 days though..i am thinking either that was the most smallest period ever or it was spotting w/ a smidge more.. funny thing is..the day I had sex on the 5th day of spotting it stopped all of a sudden and now I'm a week late..could this mean I ovulated right before my period and have to wait another week? I was suppose to ovulate on Sept 10th..
