Pregnancy symptoms?

kenzie
So my son was born in July I got the IUD at my six week pp. My period was 6 days late and on the 7th I had some dark brown/red spotting for like 10 minutes and nothing else, I'm bloated and nausea all the time I tool a hpt on wensday and got a negative, is this normal with the iud or am I really preggers and just tested to soon?
