This is my first pregnancy. I'm 27 weeks and wondering if I'm having/have had braxton hicks. I've had a couple of very brief feelings across my bump where it feels tight (bit like when you're really bloated but only for a few seconds) when I touch my bump it feels harder than normal. It doesn't hurt but isn't entirely comfortable either. Are these braxton hicks? If not any ideas whats going on? I'm not overly worried as baby is moving etc and fine but I like to know whats going on with my body and this is something I've never experienced!
