Period cramps at 9DPO?

So I’m currently 9DPO and all day I’ve had period cramp, like almost nonstop, they’ll go away for 10mins or so, but then they’re back. Has anyone ever experienced this? Is it likely that I’m just getting my period early? I’ve never experienced cramps like this unless I was about to start, but I’ve never started this early in my cycle🤷🏼‍♀️ #whatswrongwithme
