Burping

I’m 7 DPO today which is way to early to test but I cannot stop burping & the taste is awful & the heartburn is so bad. I suffered with heartburn on my son but I don’t remember how early. I never ever burp unless I drink something but I’m not burping without even having to🤢 has anyone ever had this and it been an early pregnancy symptom? I’ve read it can be it’s just so strange as I never burp without drinking
