Mirena and tennis

I needed my copper coil changing and at my appointment I was recommended the Mirena due to increased blood flow. I did not have an opinion either way and took the advise of the family planning doctor. I had not until now read any reviews on this product. I was going to make an appointment to see my doctor due to my increasing depression. I am now going to have my Mirena removed this week.
These are my symptoms to date, (5 months).
No Periods (cool)
Very heavy and larger breasts, all new bras and have to wear sports bra to bed due to very painful breasts. I cannot run at the gym and have to walk on the treadmill.
I have put on weight and this is more of a problem I cannot lose any of it. 1-2lbs a month. I go to the gym, play squash and tennis.
People have noticed my weight gain.
I feel bloated and puffy.
Feel very tired and have to go to bed in the day at weekends.
I have been feeling very depressed and have got rather worried about it.
My partner says I have changed as a person.
I did have a very healthy sex life, mostly me leading and I am now not only not bothered either way, I actually do not want any sex at all.
I feel sick and have actually been sick.
I always have a bruise and I don't know how I got it.
I am moody and have become quite lonely.
I think that is plenty to be going on with.
I have read out what all you lot have said to my partner and he just said get that thing out and he is calling the doctor tomorrow to get the snip, something we have just left till now.
I am going to have mine taken out this week so hopefully I will get back to the 'normal' me very soon.
