Does anyone here get really uncomfortable laying on their left side when pregnant? Since my 2nd pregnancy if I lay on left side I feel like something inside is being squished and it caused air bubbles to be released. IDK how else to explain it. All the books I read say to lay on left side so I am wondering if maybe something is wrong. Any thoughts?

laying on your left side take pressure off the main artery that supplies blood and oxygen to the placenta, and therefore to the baby.  i'm not sure whats causing you the squishing sensation, but try lying putting a couple pillows behind your back when on your left side so you can lean back a bit and not be 100% on your side.  a lot of women feel a lot of discomfort because they think you have to be on your left side all the time.  you don't!  being comfortable and getting quality sleep is more important.  being on the left side is really important when there's an issue with the baby, such as a drop in heart rate during labor.

When we were residents, we were made to research how some things got started in OB.


this whole  LEFT sided thing was interesting.  Back in the days when fluoroscopy was done on pregnant women ( in the days before wer knew about effects on baby)---a study was done when VERY pregnant women were MADE to lie on their back and XRAY fluoroscopy was used to see if thier major vessels (Aorta and Vena Cava) were compressed.


The Vena Cava is what is compressed--so if a woman was complaining of feeling faint--due to compression stopping blood from getting to heart to get pumped out--they had the woman turn to her side.


NOW--it just so happens that the fluoro unit was positioned in the room so that if a woman was turned to the RIGHT side---she was facing the wall and couldn't be observed.


If she turned on the LEFT side  she was facing the door and the examiners.  So all were turned to their left side.  So just getting off the back is the thing---left side right side---not so important


Get on ANY side to get the pressure off the vena cava---we flip from side to side when baby distressed.
