Implantation cramps or period cramps?

Lauren • Ttc 1 month, baby #1 due June 2019 🤰🏻

So this really sucks I’m having cramps and sensitivity in my lower abdomen so i don’t know if there is even a chance of implantation cramps or if it’s the start of my period I’m 9dpo and my period is supposed to come in 3 days which I am about 98% certain it will come just didn’t expect to have cramps right now.
