Perfectly natural, in my experience. For a while during my first tri, it felt like I was throwing up from both ends (sometimes almost at the same time). Miserable! Don't think it was anything to do with what I was eating, just crazy hormones at work. I rode it out without drugs, and soon the constipation returned... can't say I was wild about that, but second tri has been much better, so hope you will be feeling better soon!
