You either have a heart block or not. Your first step ought to be to find out whether that first EKG was correct or in error. If true, a Left bundle branch block during pregnancy may be a sign of imminent heart failure, “peripartum cardiomyopathy (heart malfunctioning)“. It could be a serious problem and you should have it confirmed or denied by a cardiologist.
Hope this helps,
