I had a Mirena IUD in for a little over 6 months.  I had a lot of complications, bloating, weight gain (30 lbs), over heating at night, mood swings, among others.  I took the IUD out about 2months ago.  Within a few days, I had what I thought was my period for 2-3 days.  I have not bled since then and I should have gotten it this last week.  I do not think I am pregnant.  I am overly bloated, gaining 5-10 lbs in a day.  I eat a really healthy balance diet and work out daily with cardio and pilates.  I am constipated at times as well.  Now I am over heating again.  What is going on?!
Hi. Thanks for asking in Chat Doctor. One of the main actions of progesterone is relaxation of smooth muscles of intestine resulting in constipation. Although you have removed the IUD IRENA it will take some more time for the hormonal effects of progesterone to get flushed out from your system and hence you are feeling the effects of progesterone. In some, the menstrual cycle resumes within 3 months whereas in others it takes a longer time for regularization of periods. Do not worry. The effects will wane off after some time. Have nutritious diet and continue your regular work-outs. I hope this is useful to you.
