Not sure if the right group but please help

So I’m gonna start off with saying I don’t ever get spotting I just ovulated the 22nd and I’m having spotting today. The last time I had spotting was last month and I ended up with a positive pregnancy test but it turned into a Chemical pregnancy and I’m just curious on if anyone has any ideas why I’d be spotting today. Also I’ve been having slight cramping too
