Uterus2. 7cm instead 3-3. 5. An advice.

During 5th month pregnancy checkup in scan we found 2.7cm cervix instead of 3-3.5cm. My Dr told its critical stage, you need to put stitches within 1-2hours. Then my DR referred an big medical collage hospital in chennai, due to in my city there is no stitching facility. We went to that medical collage hospital. We admitted in emergency ward. A doctor attend my wife and said its no bleeding and pain, so we need to keep under observation for 2 days. I told OK. After 2 days, DR called and said that now no need for stitch's for 2.7cm is OK. Because after putting stitches only so many complications comes like, bleeding,abdomen pain and mainly infection can occur. Dr told  to take complete bed rest. Now what i wanna do. A confusion some doctor's saying stitching is best and the other doctor's saying no need for stitching because some peoples have delivered their baby's with 2.5cm cervix. Now what i want to do. Very confused. Please i humbly request me an advice. Thank you all.
