Am I pregnant?

My period was late 2 or 3 days, but I’m still experiencing typical pregnancy symptoms. Such as nausea and vomiting, tender breasts, and I’m always tired. My period was a bit abnormal almost like light pink spotting, to the point I didn’t need tampons or pads for the first 3 days or so. But, my period did eventually get a bit heavier for about 2 days, then lightened up for the next 2 days. When my normal cycle lasts about 4 days. Light the first day, heavier the next 2 days, then lightens up the last day and stops after that. I still need feminine products for my entire period normally.

(Just got over the Flu about a week or so ago.)

Do you think I’m potentially pregnant? Am I just overthinking?
