I told my hinge date my period schedule?

I had a first date with this guy scheduled today whom I haven’t met before. He seems really cool and normal lol. But I got my period and canceled because of the pain. I wanted to be honest because I thought he would think I don’t like him. So I actually told him I got my period and that’s why I need to reschedule. He was totally fine with it. Is this weird? I mean his response after he told me it was totally fine was “So if we date that’s something I can look forward to once a month?” And I basically told him I get it every 3 months (which I do) and like oh my god it’s just so weird I had to tell this guy my whole period schedule. But on a serious note, guys, is this weird for a girl you never met to tell you?
