Hope someone can help me out as I'm not completely sure what they are. I've been getting what I've been told is Braxton Hicks for about 3 weeks now; my stomach goes rock solid and I find it hard to breathe a bit when this happens. But in the last few days, they've been happening more frequently, about every 5 minutes or so, and seem to be becoming stronger. They aren't painful, just uncomfortable and last for about 10-20 seconds. Is this still Braxton Hicks or could it be the start of labour as I am due in 8 days?
