Yu

Hi ladies I'm currently 33 weeks and 3 days pregnant and 8 days here in the hospital l, i was 32 weeks and 2 days when i came here at the hospital the doctor said my cervix is 4cm, then today Monday they checked again and they said it's a bit short it's already 2.75cm, I JUST WANT TO ASK IF THERE IS A CHANCE THAT MY CERVIX WILL GO BACK TO 3CM AND ABOVE ? WHAT SHOULD I DO?
