Sometimes it can happen in pregnancy because of all the extra blood your heart has to pump through your body. Your blood volume can increase by up to 50% during pregnancy! That's a lot of extra work. I had palpitations during pregnancy but it all went away after baby was born. No problems.
The doctor even says my iron is great I don't know what a heart murmur is but the doctor said I have it .. is that bad?
Yeah I have been experiencing this too and I don't know what it is but it freaks me out! I heard anemia can cause an irregular heartbeat so I've been making sure to take my prenatals with iron in them every day
