I feel almost exactly how you're describing, ash, though I'm at 30 weeks... My tum is rather on the smallish side (though babe is right on target for measurements, I look more like 20 weeks) and when I mentioned to a few older female relatives over the weekend that I thought rabbit had engaged they were REALLY suss. And I seem to be peeing every 30 minutes. Do you do any squatting sort of exercises?
