You said that your whole pregnancy
has been in high risk. Since you are in 37 weeks now, it is better to be in close touch with your Obstetrician. You need more frequent monitoring every week.
If your os is still closed and the baby has not dropped, you could opt for an elective caesarian section at term. It is a safer option for you. A trial of labour may be allowed too.
Follow the instructions of your Obstetrician.
All the best.
