Early period from clomid?

Anyone every use clomid and start their period early? I’m on CD 23 and I ovulated just 7 days ago, confirmed by OPK, and I’m already spotting. My period isn’t due for another week. It doesn’t look like implantation bleeding either, it’s brown. The only thing that changed was I took clomid on CD 3 this cycle so I don’t know what’s going on🤷🏻‍♀️

Thanks!
