It could be a number of things. I've had a few different abdominal pains...
Uterus contractions - feel like menstral cramps
Little 'twinges' on either my left or right side... no idea what those are but they aren't bad and only last for a minute or two.
Gas pains - these can get pretty bad.
If they are lower abdominal they can really ache, usually on the left side, they are generally relieved when the gas is... ahem... expelled. It can take up to an hour or so to get things moving.
Upper abdominal gas pains generally just feel achy and nauseating. It may feel like you are going to be sick... once again, let out a good blech or two and you feel much better.
Sorry if it's TMI, this is just what I am experiencing. The gas pains are by far the worst of the lot. I'm trying to eat non-gassy foods, but it just won't go away, I'm so very thankful that my hubby is understanding of my 'issues'
