They can be very uncomfortable ! Your whole belly tightens up really hard for about 20 seconds or longer. They usually don't hurt but they are uncomfortable.

My belly would get really tight and I’d get period like cramps and it got hard to breath. My real contractions were in my back so Idk what real ones feel like in my stomach

I haven’t had the real ones yet

the braxton hicks

my belly gets really tight and hard and sometimes it’s harder to breath if I’m laying down

As far as I’ve had, period cramps and back ache at same time but it’s really hard to say because mine come so random
