Chance of getting pregnant symptoms and conditions

Since getting the Mirena inserted in April of this year I've noticed a few changes in me. I've been just kind of out of it. I'm in college and that's not a good thing. I have a decreased libido, headaches all the time, pimples on my forehead, depression, etc. I've never had pimples in my life, so I know it's from that. I just feel like I'm in a fog or something. I want to get Mirena removed, but I don't want to take the chance of getting pregnant. I'm not good with remembering to take a pill or whatever, so I'm really at a loss.

I read a message above "by APAINTEDSMILE and I agree with Alesse being one of the least negative side affects...all birthcontrols are going to have a side affect.However Alesse Is one of the weaker Birthcontrol pills out there.
-I had lesser day periods(3-4)
- my period always came on thursday
-no cramps/acne due to pms
-didnt get pregnant while on the pill
My guess for anyone feeling they were going crazy on the pill is due to youre own hormone levels ..and its called PMS

However as much for Alesse as I am I went off for a week and became pregnant right away , aswell as my younger sister,she also took Alesse and is pregnant after being off for only a couple weeks b/c it is a weaker birthcontrol pill going off the pill for even a week there is a high chance of getting pregnant.But as long as you take it properly Its a great form of Birth control With very little side effects...

The person who would rather have highblood pressure then a change in youre cycle, thats crazy..THATS A BIG SIDE EFFECT.that affects youre health.once you start Alesse and you get youre period, you shouldnt get it 2 weeks later it'll just change the cycle to 21 days on the pill and 7 days or less off for youre period. give it a couple months atleast for youre body to get used to the new B.C
