Pregnant or Period 😩

hi guys i need a little help. I just finished my “period “ today but this time it was super light. I had cramps but they weren’t as painful as they always been and I get pretty bad cramps. And it felt like my ovaries were throbbing About a week before my period my nipples wore really sensitive and every morning. i would have nausea like I was sick to my stomach and need to throw up still a little today. Haven’t had these before during a period soo I’m little nervous 😩
