Skyla IUD

Jessica
I have had the skyla IUD for almost 2 years now in February. I'm now 19days late on my period. When I took a test last week it said negative and my gynecologist told me to come in so I have an appointment tomorrow. I'm really nervous and hope I'm not pregnant. I last had sex with my boyfriend November 1st and he deployed a week later. Does anyone have advice or have been through the same thing with their IUD?!
