I have a strange feeling in the top of my stomach on and off for the past two months. Its like a fluttering feeling, it doesnt hurt but is uncomfortable and tender if I press on it. I had my gallbladder removed several years ago, so its not that! Not acid reflux, indigestion or gas. I've had two late period but eventually they came on after 5-6 days. I took pregnancy tests both times and they all were negative. My periods have been lighter then normal but more painful on my first day and this time I had jelly like clots. Do you have any ideas what this annoying feeling is?
