Hi - 25 weeks pregnant and have been suffering from being out of breath easily - seen doc on Monday who is testing my thyroid as I do take thyroxin for underactive thyroid and although not anaemic my FBC was low for me so are re testing - Problem I have is I suffer with ectopic heart beats which were investigated 2 years ago and all was ok although they never picked them up- had 72 hour ECG, Stress test and ultra sound of heart - Since being pregnant they are so much worse, which I expected by last night and all day today my heart beat seems different really irregular not the usual pause and then double beat, seems all over the place - Have an ECG booked for Friday, but wondering if I should go to hospital as it is scaring me and I am feeling worried - What do you think?
