It's gas, and you could also be constipated. It's all uncomfortable but can be alleviated.
Farts are a giant part of pregnancy. Had a gassy tummy so many times. You are gonna burp and not even know it's coming. You just have to learn to go with it. Or you'll be very embarrassed.
Its most likely just your digestive system. I will be 30 weeks monday and I have struggled with gas and bloating and diarrhea and constipation! All of it! Lol but being pregnant with extra hormones it will speed up your digestion or slow it down sometimes and you will just have days ur super gassy and miserable and then days you are back to normal. Its just your body adjusting. You shouldn't worry about it:) congratulations by the way!
Me too, just already been through miscarriage so kind of anxious, no blood though.
Sounds like you just have some gas?
