Problems with the mirena iud?

i have had the mirena for about 4 motnhs now. i just quit bleeding about 2 weeks ago. for about the past week i have been getting headaches a lot, i have also been getting really shaky and dizzy/lightheaded. the other day i actually had a panic attack, which never happens to me. i was just wondering if anyone else on the mirena had gone through this. i'm really considering getting it taken out and asking my husband to get a vasectomy! (i cant make an appointment with my gynecologist til tomorrow b/c of memorial day weekend)
