IUD cramps, bleeding and stress

I'm used to heavy bleeding and really bad cramps durig my period and bad cramps when ovulating. So getting the IUD two weeks ago,and experiencing the cramps have been a walk in the park for me. In fact they've been nothing compared to what I'm used to. 
My cycle is usually pretty consistent, I realize that with an IUD there comes changes in your cycle because of a foreign hormone releasing plastic thing taking home in my body. Obviously there will be changes. But my cramps and bleeding have seemed to decrease drastically in the pas week or so but I received some upsetting news two days ago and I've noticed that my cramps have come back a lot worse and today I'm bleeding as if I'm on my period but it's not my period. We all know our bodies so we know when we're on our period or we're not. So I'm wondering if the stress of this news and the emotional roller coaster could cause my symptoms to increase and be more of a hassle? Has anyone experienced stress and IUD symptoms correlating?
