Postpartum moms!! I have a question!

Postpartum moms!! I have a question!

I am 5 weeks pp. I bled for two weeks after birth then stopped bleeding for one week. Then I bled heavily for a week then stopped for a week, so I would think that was my period. I just started spotting today. My dumb ass didn't listen to the doctor and I had sex for the first time 3 weeks pp. is this normal bleeding?
