No, it does not make sense, if the policy is “paperwork needed after 28 weeks” you should not have to provide paperwork before the 28 weeks. If what you say is a concern the policy should explicitly say “X paperwork after 28 weeks and Y proof of ‘pregnancy time’ if less than 28 weeks”.
You cannot simply expect people to produce documentation on the spot when you have not mentioned upfront that is needed.
