Hello A.,
I, too, have the same birth control. My first thought on this is you took it out too soon. It's supposed to last five years. You took it out when it still had plenty of hormones left and it's taking your body a long time to adjust to the change.
My impression is since it lasts five years, towards the end of the "dose" it lessens in strength, therefore allowing the body to adjust to the change. Before I got mine, my doctor asked me if we planned on having anymore kids in the near future. We said, "No." So he said he'd give it to me. He said if we planned on having kids, he'd recommend something that wasn't so long term.
So, I'm guessing if you knew you were going to go off it so soon, you probably shouldn't have gotten the iud. Your doctor should've told you that.
I'd make an appt. with your doctor and tell him/her your concerns, AND possibly a pregnancy test. Just to make sure either way of the outcome.
Well, I've had mine going on three years, and don't have any plans on removing it anytime soon. As a matter of fact, I may have to get another one until we can decide what we're going to do about birth control.
Believe me when I say that you're NOT going crazy!! All those emotions you're experiencing are hormones. Don't let it make you feel bad.
Good luck and stay away from sad movies!! :) ls
