Constant heartburn and indigestion..Help!!

Sheynlees
I don't know what it is but no matter what I eat or when I eat I immediately feel full. It's like my belly wants to pop and everything just makes me feel awful. It makes me feel so uncomfortable and I am hungry but I can't enjoy the after of my meal. I feel uncomfortable and my stomach feels tight as if I ate something wrong to upset me. I went to the Urgent care and they gave me something that made it go away but I can't be taking things to make it go away. I'm not taking any medications for it I just let it be....is there any home remedies for this please help!! I'm a first time mother and I need help...thank you!!
