Copper iud. Help?

R

I had a copper iud fitted 3 weeks ago. Last night i went to the bathroom and noticed blood and i started having severe cramps following a fever.

I think my iud us moved as i can actually feel the strings and the bottom of the iud. This was the day before my ovulation and i had sex. Is there still a possibility of pregnancy? Has anyone had this before? Does the iud need to be removed or can i push it back in by myself?
