Heart flutters?!

Heather • Wife and Momma to 2! 🥰

I know ive mentioned this before but I just want to make sure heart flutters are normal? It's my 2nd pregnancy and I'm 18w. Didnt get these with my 1st one. It dosen't happen every day and sometimes I get multiple in a day and other times I get 1 or none. 🤷🏼‍♀️ I've heard low potassium.. low iron.. and I've heard it really just is a normal thing that happens while pregnant. Thanks in advance for everyone's info. 😊
