Braxton hicks contractions...

Suzette
I'm 36+2 and I have been feeling really bad Braxton hicks contractions went to the hospital cuz they was 15 min apart and as a first time Mommy I got scared, they check my cervix and I'm still close. At this time should I start opening or it's ok to be close I'm scared of having a c section because I'm not open yet. Any advice!?!
