Not sure what’s normal, could this be it?!?!

🙃😜😎😜🙃

So I’m 7dpo and have had some mild cramping in my lower abdomen, mainly on my left side. It comes and goes and isn’t unbearable. I’ve already got 2 other kids and never had any implantation bleeding or any other symptoms til I was way late on my period. Is this cramping the start of my implantation? Is it too soon for that??
