I got my Skyla IUD put in in January of this year, and the two periods I've had since then have been super super heavy and I've had the worst cramps of my life. This month, my period is 10 days late (!!!!), but these past few days I've been experiencing some very light cramping for a few minutes a day and some very very light spotting (barely even enough to use a panty liner). Is this my period??? Have you guys experienced anything similar with your IUD?
