Possible?

I had unprotected sex and then got a faint positive. Then a few days later what I thought was my period came. It was really light and was barely filling panty liners. This past week I e been super tired. Like sleeping all day and nauseous badly. I’m wondering if it’s just me losing my mind or if my so close to my ovulation week and that’s effecting me or if I should just test.
