Basically you can feel your belly get stiff I think it's the weirdest feeling lol
It feels like a contraction, a contraction feels like the bottom part of your stomach gets really tight the difference between Braxton hicks and the real thing its Braxton hicks only last a minute or so and don't get longer and closer together. The real contractions start lasting longer and longer and get closer together
Its normal my sis said our body getting prepared fir the real thing ...there small contractions I get them too every day n am 33+5WEEKS
