If his sole purpose for inviting you over is to get physical, then just warn him before you go over. "Hey I just wanted to give you a heads up, I'm on my ladies days. In case you're not comfortable with that."
But if that's not his only reason for inviting you over (but still implied), then just go over and once he starts touching you warn him "it's my time of the month."
Just say throughout the day before you go to his that you're having horrible period cramps.. It's not some huge thing you need to overthink :) men are aware women have periods haha
Just say it
