Chest pain?

Gabriella
Does anyone else experience this feeling?
The top middle and right side of my chest hurts frequently, and doesn't feel the way heart burn and acid reflux do. It feels like someone is pushing their fist against your chest, and every time it happens it's unbearable. Tums do not work. I don't want to take any over the counter medicine because I don't want to hurt my baby. Anyone else experiencing this? I am 30 weeks today.
