No great thoughts- sorry hun. I'd ring your Doc and ask... it can't hurt. It is possible that with all the hormonal changes (maybe) that it's causing your tummy to be more sensative? I had tummy issues for YEARS- but got them sorted prior to pregnancy and still Ok after. That was after seeking help from a naturopathic doctor. So, if your regular doc doesn't have any great ideas, I would for sure see a naturopath if troubles continue. For me, it only took a few months and my tummy issues were all but gone-- it's rare to get an upset tummy anymore, and prior I would have an upset tummy pretty much nightly! Sometimes our bodies just get "off balance" and don't process the food we eat properly.
Best of luck!
