IUD's

Vianey
Hi! I went on the BC Pill a month ago but had to stop after 2 days because I had an allergic reaction (itchy skin, numb face/arms). The practitioner at my college health center told me I shouldn't take any type of BC Pill anymore bc they're all basically the same and I could risk having a worse allergic reaction. 
She suggested an IUD but I don't think I want a foreign object in my uterus for 5 years. What are your thoughts on the IUD? Suggestions? Do people like it?
