Help dont know if itll be okay?

my sister is 32 weeks pregnant. she had her babyshower today. well i was about to help with decorations but i had to get my oher niece cause she was somewhere she wasnt suppose to be. when i was walkin back and i was hunched over lookin at my neice i didnt see my sister gettin decorations down and i bumped into her belly with my side. kinda hardish. i feel really bad and scared about the baby! my sister seemed alright but i am worried.
