I seem to be having what feels like severe gas pains. I am normally sensitive to liquid dairy products and recently had a meal containing these things. On top of this I'm 39 weeks pregnant. I have been kept awake by severe pain. I've taken Pepcid AC for the heartburn and GAS X to try to ease the pain. This has worked somewhat but I am heading into night two of this torture. Could it be something else? I also vomitted up the balance of the rich meal and my heart rate has been about 140 for 18 hrs.
