hey, personally I do feel really bad in the first day and when I need to go to work I always think "I wish I could stay at home and work from there", so it really impacts my performance and from one side it is indeed a great idea, but it is sexism towards men - they also feel bad from time to time, so why not unify this practice for all and just give more paid day-offs / sick leaves, as was already mentioned in the comment above. Also, I am not very comfortable letting everyone in the company know when the period starts and gossip about that (yes, this is also a topic for gossip).
