Acid reflux?

I’m almost 5 weeks pregnant & since finding out I’ve been having discomfort in my chest. It doesn’t really hurt but it’s enough for me to feel it. I don’t think it’s right in the center of my chest but more under my breast bone. It usually happens after I eat something spicy or with tomato sauce. For instance yesterday I ate a slice of pizza and it happened, today I ate a bowl of chili. My stomach does feel bubbly if that makes sense but no other symptoms of acid reflux besides that and the chest pain. My heart starts racing afterwards too but it eventually resides. Should I be concerned?
