Posting again since I got no comments... im 30 weeks preg ftm. I called my ob about this problem she said to go to l&d if it persists for a few days. I can't seem to breathe very well when I lay down on either side or sit in my recliner. It eases when I stand up. It's a slight pressure on my chest. Anyone else going through this?? What did you do what was it? It's been going on for a few days I called my ob today.
