basically every day starting from 4-5 pm (and the later the worse) i have this terrible sensation of my belly exploding, stretching from inside, like I’ve eaten 3 elephants. and i literally can't walk more than 10 min, as with every step the feeling of explosion and stretching of the entire belly is becoming more and more uncomfortable, even on empty stomach. This also makes breathing difficult as it feels like everything is so stretched there’s no chance for the body to do natural expansion and contraction for in breath and out breath. I literally can't go out in the evening as with every second standing up the feeling gets worse. Even though the baby is still small, I’m only 24 weeks but it’s been progressing and getting worse for many weeks now . Any word of advise ?
