IUD Issues

So I got an IUD at my six week postpartum appt and I was super excited about it buuuuut whenever I’ve tried to have sex with my husband he’s cried out in pain and says he can feel it. I’ve already contacted my midwife and had an ultrasound done and she said it’s where it’s supposed to be and my hubby shouldn’t be able to feel jt ( she totally thought I was lying) does anyone else have any experience with this? Is there anything I can do or do I need to resign myself to using a different form of BC?
