6 days late

Dianne

Last period was 05/09/2016

I was suppose to start my period 06/06/2016. Well I'm currently 6 days late (7 if you count the actual day I was suppose to start) well I took a pregnancy test and it came out negative. I'm also on the Mirena IUD but I'm getting it taken out tomorrow (06/13/2016) I mean I have some pregnancy symptoms but that could be anything.

Any chance I'm pregnant and getting a false negative?
