I am 21 years old ive had 3 kids 1 was given up for adoption. I live with my booyfriend of 7yrs and my 2 kids, a 4yr old and a 3yr old. After getting an IUD put in that was supose to last for 5yrs I started having alot of abnormal heart beats, it would speed up and sometimes skip a beat when i got nervous or scared. I had it in for 2 weeks before I had it taken out and in that time it got worse, after getting it taken out for the first few days the pain and abnormal heart beats went way. The 4th day I started having small chest pains which at first didnt bother me but then they began to worsen when i got nervous, stressed, or scared. Eventually at night laying down to go to bed i would get pain and stay up any where from 1 to 2hrs. I read that Magnesuim would help with heart disease and at the time i was thinking i had heart paplitations so i added more to my diet and it started getting better for a week or so and then the other night i started getting chest pains again, but this time its on the other side of my chest away from my heart. I tossed an turned a couple hours before falling asleep. When i woke up this morning my back and chest was in pain and after being up walking around for a bit it started going away. Does anyone know what might be wrong with me?
