Early pregnancy signs

Anyone have cold/flu symptoms as an early pregnancy sign? I have been very sick feeling that past few days and have had a cold for about a week or so. I had my period It was not light but not heavy either. But a few days after I was nauseous, cramping, exhausted, smells bother me now. Idk if it's just the time of the year being flu/cold season or pregnancy or just something else altogether any ideas? Can you have a period but still be pregnant?
