its actually super easy to use the other bathroom! my advice is try to make sure there is actually space so you don't have to stand awkwardly waiting and questioning yourself. You also don't need to talk to anyone, most people just want to be left alone. Also, 99 percent of the time, no one actually cares. most of us (people who use the womens rest room) are too busy either praying no one can tell that we're on our period, trying to finish quickly so we aren't late, or just ingoring everything else and busy with our own thoughts
