First post Mirena period, feel like I'm dying.

I had a merina IUD implanted six weeks post partum after having my youngest and had it removed less than a month ago, I was  amenorrheic and have not had a period in over six years, glow is predicting that mine will start tomorrow and honestly I feel awefull. Has anyone else had a rough first period coming off of their Mirena? How long did it take for your first menstruation after removal?
