Has anyone had chest pain at 20 weeks pregnant?

I’m 20 weeks pregnant and it started last night I felt pressure on my chest . But it wasn’t as bad until 4am when I woke up no matter which side I layed left or right it hurt . It felt like pressure and it was very uncomfortable but I can still breathe fine. I never had this type of chest pain before not even before my pregnanacy . This is my second pregnanacy btw. With my first son it was smooth and didn’t feel chest pains or anything . I’m having a baby girl this time. I did go to the Er and they said my heart rate and blood pressure was fine blood tests where fine but he asked me what I ate night before and I said spaghetti and he said it probably was the tomatoe sauce that could probably cause acidic reflux . And he said for me to try avoid tomatoes and spicy foods. But I always ate tomatoes and had spaghetti couple times and I didn’t feel chest pain and that night that I ate it I only ate small amount cause I been throwing up in my pregnanacy so I can’t really eat a lot. And I don’t eat much spicy foods only sometimes but I can only handle small spice . But I still make sure eat for my baby girl and I’m always careful on what I eat when I’m pregnant . Has anyone had this happen to them? Could it be that maybe it’s just my body changing to make room for my baby?
