Ab exercises symptoms and conditions

I wish i would have found this web site 2 weeks ago. I have to kids and married.Husband didn't want any more kids but i wasn't ready to get my tubes tied. I'm only 24 years old. So my doctor suggested I get Mirena. I thought it was a great alternative. So 2 weeks ago i got it. Haven't stopped my period since. I even am breaking out under my armpits. VERY PAINFUL too. There swollen so bad that it hurts to swing my arms. Not only that deodorants makes it worse. Has anyone else had this problem!!
As far as the tiredness goes, yes i also have noticed that also. I hope I don't loss any more libido. Thats already a big issue in my marriage. I am already thinking about taking it out. OH does anyone know if it is safe so do ab exercises while having mirena. Thanks everyone.
