I think it's hilarious that some men are shocked - SHOCKED!!!! - to find out that many prossies will work during their periods. If they can't tell, then what's the problem? And the assumption that we should reduce our income by up to 25% just because of something that can usually be successfully concealed is absurd.
That said, I take the pill without pause in order to avoid having periods. If there were to be any sort of spotting, I have those sponges that are sold on Amazon (they're sold as alternative tampons) and they work great.
