Skyla and Sex

I got my Skyla put in two weeks ago and I've been spotting on and off (mostly old, chunky blood tmi sorry) but with no real cramps or anything. I stopped spotting for a few days so I was pretty excited thinking that maybe it was over and my body was adapting to my new friend! I had sex 3 times on Saturday and I started spotting again. I'm not sure if this is just a coincidence, or if it has something to do with Skyla. I checked my strings and they're all good and feel normal. The spotting is a little heavier than the previous spotting but I may be imagining that because of my anxiety about this. I have no cramps/pain or anything of that sort. Has anyone else experienced spotting after sex? Or have anything thoughts on this? Thank you so much!
