I'm not sure whether I should go to the doctor or not.. I have just been reading up on my mums condition which is cardiomyopathy. Whilst doing this I have found information on peripartum cardiomyopathy. I am currently 6 months pregnant with my 2nd child. I am 24 years old. During this pregnancy I have been having chest pains(other than the normal heartburn), strong palpitations,extreme fatigue, abdominal pain and have been waking up suddenly in the middle of the night unable to breathe.. well I can breathe but not get a full breath. Also when this happens I have really strong heart palpitations. I can only ease it by sitting up slightly and going into fresh air. I just thought this was a combination of being pregnant and thought that I had somehow developed asthma. I was using mt partners asthma puffer to try and get a full breath again but it never worked. When this happens I usually have trouble breathing for about half hour..... This usually happens 2 or 3 times a week...
