Insertion

Im getting the Kyleena Iud inserted next week and I'm really nervous. I get really nervous even if my boyfriend tries to touch that area sometimes so I'm terrified to have a stranger do it and i'm scared it's going to hurt. I am really sensitive to pain so like if i get a sudden shock of pain or see any blood i will pass out. what should I expect for the day of and a few days after?

Also is it safe to have unprotected sex with just the IUD
