IUD advice

Kara

Hey! So me and my boyfriend haven’t been together that long, but I have the Kyleena and recently he has mentioned that he feels something poking him a little when we have sex. It only happens occasionally but my sister mentioned that I should switch over to the IUD that she has which is good for 3 years. I’m just scared tho because when I got my IUD put in it was the worst pain ever and I threw up at the lady doctor office and it was just a horrible experience. Would switching over do any good?
