Alright, so I'm a little confused. As far as I know I haven't had any Braxton Hicks Contractions, BUT the top half of my belly gets like ROCK hard sometimes. And it doesn't necessarily feel like baby girl pushing or kicking, it's just this huge pressure that lasts for a couple minutes. I can push on the area and it usually doesn't hurt, and sometimes it even goes away - but I don't know what it is? I've heard BHC can be completely non-painful, so is that what I've been having? I thought those would be in my LOWER belly? TIA for any advice/tips!!
