I'm not quite sure..

I'm 9 wks postpartum from having my daughter and I have the copper IUD in since about 6 weeks.
 I took a test last night ( 1st pic)since my period didn't show up yesterday.
Now this morning I'm having a extremely heavy period with some strange clots.. But I had one more test so I tested again ( 2nd picture) 
I don't know if these are Evaps since I know blue dye can do that.
Or if I'm having a chemical pregnancy or what's going on.
