Period in 3 days!

Esthefanie

So my period isn’t due for another 3 days but i decided to take a pregnancy test because i was feeling a little curious. But once I took it there was a an obvious pink line and when I held up the test close to the window where their was light I saw another line but it was clear. Could it possibly be a positive of a bfn. Has it ever happen to you ladies? Just curious
