Please tell me first period question?


I had my son 5weeks and 2days ago and i stopped bleeding a week after having him. My stupid self had sex way earlier then I should've. Three days ago I wiped and i noticed a slight amount of pink blood barely any! And from that day on it brownish clots and slightly pinkish red blood but not much at all not even enough to make a mark on pantie liner but just to see when wiping. I've been cramping and moody to the max. So my question is after a vaginal birth was your first period heavy? Or the same thing as mine? Or am I probably pregnant I'm gonna test next week but I'm curious if this normal or very not normal.
