I've had it off and on for about a week or so. Don't know what could be causing it. I've heard acid reflux, pregnancy, etc. I had some increased burping over the past couple weeks, but it has subsided; had some acid once in awhile. Negative HPT's and blood preg tests, so I know it's not that (took those because I'm normally paranoid and wanted to be sure! :-) )

Any thoughts? Yes, I'm going to go see the Dr., just wanted some insight. Thanks!
