Okay so I was just sitting on the couch and felt my uterus tighten for about 5-10 seconds, it wasn't extremely painful(more uncomfortable really) but it definitely wasn't round ligament pain. It was only once and didn't happen again. I was hydrated so I'm thinking maybe Braxton-Hicks I heard you can have them this early, just wondering if anyone else is or has had them around 17 weeks?
