IUD so far

So I recently got Skyla inserted 2 weeks and I have been experiencing things that are making me question if it is normal, I would love feedback if any of you know the answers or have experienced the same thing. First and foremost- I'm having pain during sex. I have been reading posts lately though and have seen that it is most likely linked to not being "turned on" enough. So I would say that skyla has made it harder for me to get turned on. Also- I have had weird discharge, but only when I wipe? Ha I know that's gross but it's weird.. also I have gained 5 pounds since getting it 2 weeks ago but that was a side effect I've seen in other women as well- it's just such a let down and making me lack in self confidence :( my main question is how do I get over being in pain in sex bc it is so frustrating
