Could I possibly be pregnant

Bridgett

I have been extremely nauseous and fatigued all week. I was 5 days late with my last cycle, took 2 tests and I thought I saw faint lines on both(my husband didn’t). But when I started my period it only lasted 3 days. My cycle is never late and is usually 5 days long. I dont know if I could possibly be pregnant because I had a period. But I want other opinions. Should I re test tomorrow? Or am I overthinking things?
