IUD VAGINAL DRYNESS AND BURNING

So I have been having the Skyla IUD for over a year now. I've been experiencing vaginal dryness for about 2-3 months now. I used to be able to get wet so easily and now it's like a desert. I'll get wet but it takes awhile for me to get wet even when I'm really turned on. It's starting to bug me a lot and after sex I've been feeling burning in my vagina opening. It burnsssss like crazy. Also, the smell has been stronger then usual, I don't know why but it gets so strong sometimes and I'm not if it's due from infection. No weird discharge from what I see. What are your opinions? Should I switch or what methods should I try before I think of switching? Also I've been feeling pressure in my rectum lately and I'm not sure what that is exactly, please help me😔
