I had mirena iud in for exacty 5 years and never had a period. The night before it was removed I had sex. The next dayit was taken out and I had paragard inserted within minutes. I had bleeding for a couple hours then 2 weeks later my period stared.  I have since had 3 periods which were heavy lasting 3 days.  Ive had loss of apetite, fetigue, sore lower back.  I know some women can get pregnant while having an iud and Ive read some women do beed what seems to be like a regular period though pregnancy. I dont have insuarence and I dont know if I could be pregnant or peranoid.
Hi, welcome to Chat Doctor forum.  Previously you had IRENA, which is a progesterone containing I.U.D, so you did not have the periods.  Regard is an I.U.D, which contains only copper coil, and no harmony. So it can only prevent conception, but can't stop the periods.  In early days there may be heavy periods, but the body may become accustomed for its latter.  If the over bleeding and the and the backache is continued, you have to consult a gynecologist for excluding the infection, and to remove it.  By no way it is pregnancy, still if you want to exclude you can have H.P.T. Wishing for a quick and complete recovery. Thank you.
