Congratulations first of all...

The follow up really depends on your signs. Also based on how much water left in womb when arriving at the hospital. When you are getting contraction, reach faster to hospital and it’s no wrong to be in the hospital day before than being somewhere else.

Gynecologist will check once you are admitted.
Do not worry frequently trip doctors will check about the length of openings. At some point if you can’t bear the pain and keep on asking the doctor about pain, they will ask you about epidural. Some say not to take epidural because they’re feeling it even after few months. Pink book you will submit immediately after your admission. Don’t worry nurse will take care of these things.

Just keep an eye on time of contraction and sometimes doctors won’t do scans frequently to check the cord positions. So in that case c section is the only option. So ask the doctor is everything okay with baby position and all.

All the very best. Hope you keep a bag of necessary items for baby to give to nurse upon admitting.
