I’m 21 weeks and in the past couple of weeks I started having this most uncomfortable sense that I’m about to explode, particularly after meal and especially so in the evenings. It pushes on the lungs giving a terrible sensation of breathlessness, particularly when standing or walking. The belly seems to be much bigger in those moments like I’m 9 months pregnant. Whereas in the morning when I wake up I can nearly feel I have a bump. Anyone experiencing this? Anything could be done?
