So, I had my last period Jan 3rd it is now feb 16th... I started spotting very very lightly on the 14th(only showed when I wiped and very little in my underwear... not a period I have ever experianced)i have had a couple days of light nausea around when I should have started but other than that no pregnant. Signs or no signs of starting my period. I've taking 4 at home test and one in the doctors office.. All negative.? My question is why am I spotting 2 weeks after a missed period? Anyway it could be implantion bleeding this far along?

Only time will tell, it is possible to have a really low level of the pregnancy hormone this early on, so that the tests will show a negative result.

I would suggest you repeat the test, first thing in the morning, the level will be the highest at that time.

If it keeps coming up negative. And you still don't have your period, go back to the doctor to make sure there aren't any other health issues going on, you can also ask for an ultra sound.
