This was literally me last night. I couldn't even lay down from the gassy stomach pain and I was so nauseous. I basically paced my living room the whole night since walking seemed to help. I am guessing it might be round ligament pain, but I questioned acid reflux too as I've been diagnosed with it and it was bad during my last pregnancy but not quite the same symptoms. Im terrified it's going to happen again tonight. I've felt mostly okay this whole day just a litte bloated, but the thought of a repeat of last night and another horrible night of sleep sounds just awful. And I just got my BFP the other day so if I have to endure months of this, I don't know how I'm going to cope. Hope you get some answers/help at the Dr. I'll be bringing it up too when i go.
