I wish you the best w/ this pregnancy! I am 6 weeks post-mirena and started my period yesterday! Yay! From what I read symptoms seem to ease with each cycle, so I'm glad to get back on track. I was wondering if you can explain what exactly your heart palpitations feel like. I get this feeling of blood rushing to my chest and throat area. Like when you get up too fast and you get a head rush. Same feeling just in the chest area. It doesn't seem as bad since Mirena was taken out, but it hasn't gone away. It is the one thing that I can't put my finger on. I am thinking of having them check my adrenal glands and see if they are out of whack. When I have that feeling I seem to feel revved up, sort of out of breath. I need to take a deep breath and slow down. Who knows, just relax as best you can and think of the miracle baby your carrying! Please keep us posted!!!
