Implantation Bleeding

So I have past my ovulation date and was active. I had really really really light pink bleeding for two days(on and off) and then never seen anything again. This was about a week or so ago. I’ve been excessively tired. Somewhat sensitive when it comes to smelling certain foods( smelling Taco Bell made me sick). Major heartburn. My period is due in a week. Not sure what to do.
