30 weeks weird breathing

An

Im a little concern. About a week ago I’m starting to feel breathless which I read is pretty normal during the last trimester. However I’m experiencing a very weird like breathing obstruction. I kind of feels like my throat relaxes to much and get obstructed like for a second. It happens like all day, kind of like when I look down or something like it. I saw is common while sleeping in the third trimester and for longer period that also causes snoring but mine literally last a second.

I tried finding something on google but it seems no one else experience this. Does it sound familiar?
