First period after baby. HELP

Jennifer • Michigan girl, husky lover, and happily married

So my husband and I had sex on the 18th of October. My first period was November 1st which is almost a full years after my son was born. (Birthday 11-12-2018). My period was kinda light and not really bright red at all. Is this normal? It lasted until the 7th, but the last 3-4 days was spotting only. Could I be prego? I’m not using any birth control.
