Im 21w 6d ad went to the OB today and he has referred me to a cardiologist for possible heart arrhythmia or palpations. Does anyone have any experience with this? Should i be worried? Im kinda freaking out about it! I was experiencing blackouts and dizzy spells and he thinks this is the cause. Im worried about me working now with this pregnancy, possible early delivery, any negatives im freaking out. Someone help! Lol
