Not sure if what I'm feeling is heartburn or baby pushing on my organs. I get this near constant feeling like I'm choking or have something stuck in my throat. I'm 31 weeks, so I'm partially figuring that it's the baby pushing on my organs, but I'm still really concerned. This feeling makes it hard for me to eat, makes it hard to breathe, and makes the already difficult task of sleeping even harder. Any advice will be VERY much appreciated as I would like to avoid an unnecessary trip to the er.
