It would be helpful for mothers like myself who have no choice but to have a scheduled C-section, to have the option to change the due date to 'scheduled date' without the app assuming we are farther along than we are. For example, due to uterine surgery, I cannot carry beyond 37 weeks and I cannot change my due date without the app assuming I am three weeks further along than I am, thus giving me information that is not relevant to my stage of pregnancy.
