My sex drive is gone 😩😩

Since I got the Mirena IUD (about a month and a half ago) I have had no sex drive! My boyfriend thinks I’m not attracted to him and don’t want him anymore but that’s not the case at all. Idk what to do 😔😔 has anyone experienced this? Did it go away?

ETA: I’ve told him that I feel the hormones are affecting me and he thinks I’m just making something up 😔 he doesn’t think hormones really do anything...... typical 26 year old male.
