Is arm pain normal?

Hello expecting mommies, I was just curious if any of you ever had, or is experiencing any kind of arm pain during your pregnancy? I've been having some minor pains every now and then. I worry that it may have something to with my heart because it's my left arm. Also I've been experiencing some heart burn so idk if that has something to do with it. I talked to my obgyn and she didn't really seemed concerned but she did tell to make an appointment with a DR just to check things out. I am making that appointment but I just wanted to see if anyone else experienced this. Thanks in advance! ❤️
