Forgot to say, if you have had cervix issues, you must remind your gynae about checking for a condition known as incompetent cervix. That's when the cervix opens prematurely causing late miscarriages. This usually happens into mid-second trimester when the baby is heavy enough to exert weight on the cervix. Usually people don't know if they have this condition until after at least one miscarriage this way. A friend of mine lost her baby at 22 weeks and even held him in her arms before he died, after her cervix opened. The problem is easily prevented. For her next pregnancy, her gynae made a suture in her cervix at 14 weeks to prevent it from opening prematurely again and she went on to have a successful pregnancy.
