I have what feel like af cramps at 10DPO?

Usually I get cramps the day before my period until like 2 days into it before symptoms aren't so shitty. I'm only 10dpo and af is due in 4 days but I keep cramping in my uterus (on and off) and kinda all over pain. My right ovary is getting more of the throbs. there seems to be a lot of gas/bubbles down there too. In my uterus and intestines. Af pleaseee dont come early. Shes been on time the last couple months though.
