Are cramps a bad or good sign?

Hi ladies, I'm
​10dpo today and since 9dpo afternoon have had on/off cramps in my uterus, it's like a period cramp but not painful, just enought for me to notice its there. I never have period pains until the day before I'm due on so it's too early for period pains as never had them that early but also never experienced cramps with my last two pregnancies (I misscarried those two)??
