A few OB’s will do an internal examination from as early as 38 weeks. I have no idea why they would do this. An internal at this stage in pregnancy will not give you any useful information. I once asked an OB why he wanted to do an internal on a woman who was 39 weeks. He said that he wanted to check if the cervix was still closed. I said to him ‘you would know if the cervix was opening as the woman would be in labour’. I don’t think he liked this comment.
