Belching as a pregnancy symptom?

Christian • Born 39 weeks and 1 day!!!
Has any one ever experienced excessive belching in early pregnancy. I'm 7dpo and today it's been nonstop belching and heartburn. I'm NEVER like this, nothing is helping the heartburn or belching. Also my cervix is really high and really soft, almost feels swollen. Just curious as to what people say. These are not typical PMS symptoms either...
