My bellys starting to get extremely tight and showing pretty big & my little sisters are very impatient & earlier I was standing in the door way sideways & she slid past me & didn't hurt me bad but rubbed against my belly pretty hard & slightly elbowed me, I was having major cramping & it felt like my muscles were tightening & untightening. It lasted about 20 mins & I threw up. I'm not sure if that's normal braxton hicks type pain or something bad happened, I feel fine now but & he's kicked a few times. This isn't the first time this has happened to. I figured its just that my belly's stretching and getting sensitive
