Hi Doctor, I'm 31, 5'3" 60 kg and in the 12-13th week of pregnancy. I've been told that I may have a risk of short length of cervix which would be tested at 16th week thru scan. Is there anything I can do to avoid the risk in future. Like yoga, or kegel exercise or anything to avoid? Should I be worried. They said worst case scenario is a cervical stitch. I'm scared if this may hamper normal delivery. Suggestions and little positive encouragement please.
