31 weeks pregnant & constant upset tummy with no other sickness? Please Read.?

I am almost 34 weeks now and until about 5 weeks ago, I had the same problem for about 1 1/2 months straight. No kidding! When I told my OB, he told me to eat more plain foods to help....like rice, toast, applesauce, etc. It was really, really hard for me to do that but I tried most of the time. That didn't seem to help. I was then told to stay away from dairy. Do you know how hard it is to stay away from dairy! So, that was really, REALLY hard. So, I ended up just dealing with it for about a month and half. Then it just -- disappeared. Out of no where it was gone. Since then, I've dealt with it for a week or so but then went back to normal on its own again. I didn't talk to my doctor about it anymore after the first two conversations since he didn't seem too concerned about it when I did talk to him and all of my tests have been coming back fine. It's kind of embarring to talk about the big 'D' even if it's to your dr. If you can try to eat some plain foods and stay away from dairy, that might help you. I just couldn't do it all meals all week so I didn't get to see the results. Stay away from fried foods for sure. Good luck!
