GERD and chest pain

Did anyone have GERD after pregnancy? If so what were your symptoms. I’m trying to figure out what’s going on with my chest. I’ve felt pressure in my chest like somethings sitting on it which is constant but I’m also feeling like somethings coming up my throat and gets stuck. It’s hard to get a burp out sometimes. I’m more worried about why my chest is feeling like this because it’s all day long. I’m 7 weeks post partum and just began feeling like this 4 days ago. Went to the hospital to make sure it wasn’t a blood clot even though I did not have a c-section and all test came back normal.
