Chance of pregnancy symptoms and conditions

Ok... so I've gone nearly a year without a period with my IUD. Now all of a sudden I start spotting and have awful cramps. I have not been intimate so I know there's no chance of pregnancy. Has this happened to anyone else?
Mirena mustn't been created by some evil ignorant egotistical male who believes women should be tortured. Wish men could get some sort of IUD inserted into their b***s so that we wouldn't have to be the ones to worry about pregnancy.....

I'm almost 20 years old and started taking BC to regulate my periods a few years ago and help with extreme cramps. I started on Yasmin and was on it for about 5 months and then started seeing a new OBGYN who suggested trying Yaz. I was on Yaz for about a year and a half and it worked great. But then I started getting really painful ovarian cysts. To help with the cysts my doctor switched me to another BC which made me extremely depressed and emotional. Now I am finally on Femcon FE and have been fo about six months. I haven't had a problem with another cyst again and things were working out fine... until about 3 months ago I skipped a period. No big deal I thought to myself, it is definitely not possible for me to be pregnant, its been over a year since I've had sex, so i figured it must just be stress or the way I'm eating or something..

Well it's been 3 months and still no period. I know most ladies would love to not have one but I'm starting to worry if this is something that is normal. I honestly don't know if it has anything to do with Femcon but I have a strong feeling it does because I haven't been stressed, my eating habits haven't changed and I know it is not possible for me to be pregnant. I am going to see my OBGYN soon if I still don't have one after this next pack but I am just wondering if anyone else has experienced the lack of a period as a side effect of this medicine because on this site I mostly only see women who have it too often.

mirena DOES NOT prevent ovulation!! meaning you will still ovulate, but the sperm and egg cannot implant themselves which in turn will cause a miscarriage!! This is the same for all iud's, For some unknown reason docs will not tell you this, but my doctor did and strongly advises not to use iuds!! You will get pregnant! You may think your having a heavy period but really you could be passing a dead fetus! Sorry to be so blunt, please do research before you choose this method of birth control
