I had those exact problems and within a week of having it out I was feeling back to my normal self. Even DH saw a difference. The obgyn at the clinic said it's something 1/100 complain of and it just meant it didn't suit my body. I am guessing you will be the same. Don't put urself thru it. Get it out and work out some other for of contraceptive. The bleeding non stop and the cramping and tiredness....all so familiar. Just be warned, maybe it's just me, but I used to have 29day cycles and after I had the IUD removed, my cycles are now 24 days.....wondering if that is a side effect of it?
