Feels like an EXTREMELY mild tensing low down in my belly and belly feels super hard. Initially thought baby had moved and it's back was pushing against my belly just under belly button. Only last about 8-15 seconds and then seems to un-tense. Just read about braxton hicks and sounds like it could be what it is. Only ever happens once as opposed to happening lots of times in a row.
Sound like braxton hicks?
I'm 25 weeks tomorrow. Very curious!
