My situation is just like you. Nausea and vomiting eased, but bloating and burping continues, but I don’t vomit on everything I ate, only when I feel that I ate too full and too bloated and I will vomit, usually before I sleep. I am also constantly worrying like my pregnancy is gone because my first pregnancy was a missed miscarriage. But I guess everything will be fine. I am so looking forward to my next scan in few days time, hoping that the heart is still beating hard and strong!
this is called the second trimester bliss. the stretching of uterus is for the baby to grow, it can also be round ligament pain. enjoy it. it’s very normal.
