Pregnant with Copper IUD?!

Alexis • Im 27, you can call me Lexi 💕 First time mommy to a baby girl 👶🏽🎀 now baby boy 👶🏽💙 Was pregnant with identical twin girls💕 Guardian Angel 👼🏽 4/26/17 Miracle Baby 💕🎀 12/13/17

It will make a week tomorrow if I dont get my period. I took a test last night and it said Negative.. but I am trying to find out if if it would say negative because I do have the Copper IUD.

I had cramps 2 days ago so I thought I had my period but nothing. Now no cramping, no bloating, no acne (I usually do before my period).
