Thanks for your query,
I can understand your concern. Actually single loop of cord is quite common and in most cases vaginal delivery
remains uneventful provided proper monitoring is done. In case of double loop of cord around neck, risk of tightening is very high in case of vaginal delivery, so CS may be preferred. It may some times resolute itself . You should take proper rest, relaxation and keep a count of baby movements. In case it is less then you should contact your OBG immediately as it may be due to entanglement.
Best of luck and take care...
