What do you think?

Okay I did my IUI at home on December 10th my. Started on the 29th but it only lasts for 2 days the first day was very dark as if it was ending in the next day was heavy. and then 2 days after that I bled a little bit more my. Usually lasts 5 to 6 days. I haven't took a pregnancy test because I feel like since I bled I must not be pregnant and I don't have real pregnancy symptoms or maybe I'm just playing with my mind because it does feel like my mouth taste like silver or pennies, my breast is still kind of sore, I have light headaches and little cramps here in there. I guess I haven't even took a pregnancy test is because I feel like I'm might not and why-open the wounds even more but maybe I am. Am I the only one that's crazy?
