Period after baby!

I had my daughter one year ago and have been (and still am) breastfeeding. Two days ago I thought I had started my period. Cramping and went to the bathroom and had a fair amount of blood in my underwear. But it only lasted that day! Lol is this typical? Our nursing sessions have dropped recently so I’m not shocked, just wondering if it will come back full force or if anybody has had the same thing happen?
