Happens to me alot. Your heart works harder due to the amount of blood needed to be pumping around your body so thats what causes it apparently, I find some days are worse than others.
Ok thank you, I never had this before. So I got scared.
I get that too. My dr said its heart palpitations. As long as you don't pass out when it happens its normal to get them. Id say something to your dr just so they are aware its happening. A friend of mine told me that her dr described the work our body is doing to make a baby to about the work of 10 mountain climbers. I feel like if that's the case my heart should be in good shape after this baby comes haha. Good luck :)
