I'm 26 weeks and feel like I've been experiencing this for a good while now. Every now and then I'll get this sudden shortness of breath or tight/restricted feeling below my chest/breastbone. I think I've realised that it happens when the baby moves/changes position (in a sliding across my uterus kind of way), but I can't be sure that that's the only culprit. It can be quite frightening and usually lasts up to about a minute. It happens mostly at night, and sometimes I wake up in a panic to it happening. It's not exactly that I'm gasping for air, but something feels tight, restricted and cut off slightly. It's an odd sensation to describe. I can't even tell if it's my heart or my lungs that's affected (if any) - maybe it's just the baby squashing my organs temporarily, pushing them upwards?
Anyone else experience this? Just trying to understand if it's a benign pregnancy symptom or something a little more serious? I've been getting it a lot these past few days.
Thanks!
