Skyla IUD experience!

Hey everyone,
I had a Skyla IUD inserted about three weeks ago and I just kind of wanted to see if anyone else has one and what their experience was like. 
I've been spotting pretty consistently since the insertion with some days heavier than others. I've been pretty bloated, too. I indulged in my cravings probably a little too much at the beginning, but I've been back on track and I'm worried I'm starting to gain weight because of the device. 
I hope I'm just looking too far into it, but if anyone has experienced this it would be great to have some input!
