Gas pains, or something else?

Can anyone relate? Sorry if there's TMI... But I've had bad gas for about 2 days now. The problem is that it barely comes out. I'm always constipated, and the gas seems to get trapped inside. With this extreme gas, (what feels like) my uterus is really sore, and hurts when lightly pushed on. I can't tell if it's my actual uterus that's sore, or if it's gas related and just so happens to be right in the same spot. I felt something similar a few weeks ago, also had gas, and it went away in a few days. I just don't want to ignore it if it's something more. Has anyone else experienced this!? I thought I'd check here before alerting my midwife, since she's not available at this hour anyway. TIA!
