It sounds perfectly normal Juniper. I have it all the time before and after meals and all through the night. Doc said it is heartburn/reflux. You can take zantac if it gets really bad. I still have MS so can't say whether it is a contributer or not as mine hasn't stopped. It is uncomfortable though and a pain in the butt!!! Unfortunately it is just another lovely symptom to let us know that we are indeed pregnant!!!
