1. Cook food for her (if you can cook it) or buy her something she likes to eat, because the girl doesn't want to move much during her menstruation.
2. Watch some funny movies with her. If she doesn't like funny movies, watch some relaxed and happy ones (avoid horror movies).
3. Talk more. Girls seem to be very soft hearted during menstruation. She will think you are considerate.
4. After menstruation, you can make jujube soup for her to drink. If she drinks it during menstruation, it will flow a lot. Remember to remove the seeds, which will not be so dry.
