Heart pain? Indigestion? Can someone help?

[Ros2023]

I am 12 weeks pregnant and for the past 2 days I’ve been having what I would call heart pain. But I have a feeling indigestion can feel like this? I don’t actually feel like I have indigestion apart from having pains in my chest what I would say is my heart? If I breathe in too deep it can hurt or I can randomly just feel it.
has anyone else experienced this before?
I am assuming it’s pregnancy related as I haven’t really had this before.

It does sound like indigestion! Could possibly be trapped wind too, I often have a horrid pain in my chest but in my back due to that
