Pregnant or not?

Roxanne • 25 years old. Married. Mother of two and another on the way... 🙏🏽
So I haven't started my period I was suppose to start last Wednesday and I'm usually regular. so I waited out till Sunday took a test this morning and got BFN. I have been feeling a little nauseated, boobs are tender, vagina pain, a little twingy feeling here and there, could these be signs of early pregnancy?
