It is very common to develop a soft heart murmur in pregnancy, and this can often be heard at the end of the first trimester. This is known as a ''flow'' murmur, and the sound is created because of the extra blood being pumped from the heart and can be heard by a doctor pressing a stethoscope onto your chest. It does not mean that there is anything wrong with your heart or heart valves. This type of flow murmur can usually be distinguished from the serious rare types of murmur, especially if you didn''t have a murmur before you got pregnant. |
