Does levosert coil cause migraine with aura?

I got the Levosert fitted 10 days ago so can't comment on longer term side effects but so far haven't noticed any except for the first few days after fitting. I was worried about how much it would hurt as I haven't had children and am very petite (not sure if that makes a difference). The fitting itself was painful, but it was over so quickly it was definitely worth it. I think there were 2 or 3 times during the procedure where I felt intense pain but each of these lasted literally a few seconds each. I had 3-5 days of discomfort similar to period pains/back ache afterwards and feeling a bit rubbish as a result, but nothing awful (not worth a day off work). I had some bleeding after the fitting and some weird solid white grissle stuff coming out for a couple of days. Since then I've felt absolutely fine physically. I couldn't feel the strings (tried as soon as I got home and everyday after for a week), which I was worried about. I went back to the clinic for them to check. They said its fine but the combination of my short fingers and (newly discovered!) high up left sided cervix means I am unlikely to be able to feel them. That's the only thing that bothers me slightly as you're supposed to check the strings every month. Knowing it lasts 6 years is great and I wish I'd got it years ago
