Rumbling in my vagina and lower stomach pain. Early pregnancy?

Hey so the rumbling is basically what you feel when your hungry in your stomach but down there. Ive felt it before on my period but never before and ive had some lower stomach pain. Could this be implantation? Cuz i could be pregnant cuz i had sex when i was ovulating but wont kno for a few days. Has anyone expierienced anythin like this in early pregnancy? Any opinions are welcome, thanks!
