Anyone ever gotten pregnant 2 days before period?

Hi all. Im a mother of 2 children who has always gotten early pregnancy symptoms although I dobt remember how early. I did get pregnant with my daughter 6 days before af was due. My periods are also very regular. Anyway, I was due for af on the 7th. I had my usual preperiod cramping. I had on the 5th abd 6th and im still waiting for af. Is it even possible I concieved this late in my cycle? If I had cramos doesnt it mean ny body was shedding the egg? I have sore and have been overly emotional. if I was pregbant, and say about a week along, is it possible to feel symptoms this early? Looking for personal experiences thx
