Got a question

JESSICA • I am a 28 year old mother of a 3year old little girl my husband and I got married this last June and are trying to grow our family
Ok so I had a "normal" period the end of last month and I was do for af to come back on the 19th of this month but it came the 20th and was gone by the 22nd. Could I still be pregnant or is that long enough to be called a period.
