Steph symptoms and conditions

I had the Mirena IUD inserted in September 2007... BIG MISTAKE! I paid $550.00 for the stupid IUD & another 225.00 for doctor fees!!
Okay here's my story.. I have three children, 26 yrs old, married, 120/122 pounds.. can stay in shape/get in shape easily, happy, VERY short 3-4 day periods.. BEFORE Mirena..
Now.. its been 7 weeks.. And even though I keep to the same diet, I have gained 8 pounds! I have been on a period & constantly spotting for 15 DAYS~ oh yeah.. AND bad, bad, bad, BLOATING!! Yesterday I had Severe Cramps- my doctor is out of town so the nurse actually called in muscle relaxers to help with the pain.. I was in TEARS yesterday. I NEVER EVER had menstrual cramps before.... to make things worse..I am so moody & I hate my quick temper. I have never had acne, but now I get a few spots.. not so bad, but I shouldn't have any. I feel like I don't have control over my body.

My appointment is for this Thursday.. I am getting this thing removed, so I can return to normal!

Before getting this awful thing ( which hurts when inserted & bad cramps afterward) I was using NuvaRing for two months.. I did not have any of these bad side effects with NuvaRing... I am going to try that again.

IN SHORT.. I PAID over $800.00 for severe cramping, 15 day long periods, constant spotting, brown discharge, EXTREME BLOATING, huge weight gain, and acne!! WHAT?!? I want a refund!!

Am I going crazy? I've been taking yasmin for only three weeks, i started having horrible back pain a few days ago that wont go away, and for the past three days i've litterally crying non stop and i dont know why which makes me cry more and have been very short tempered with my boyfriend over stupid things that dont matter at all. bless his heart because he probably thinks i'm crazy...I'm really considering stopping it because the only reason i was put on it was because i had a cyst on my ovary and its gone now so i figure from what everyone else is saying the sooner you quit taking it the better.

someone please tell me i'm not going crazy

thanks,
steph
