A week late

Jo

I’m a week late today. Had a negative pregnancy test on Thursday. (Cheap 88 cent one from Walmart) no pms symptoms. I’ve only had unprotected sex twice this month both being like 5 days after my period ended. Should I test again? Could Ir have been negative then and a possible positive now? Or just wait for my period to come? Last month I was like four days late and ended up getting my period. So I don’t feel like getting worked up like last month.
