Bleeding more at 3 weeks post partum

I had lochia for 12 weeks and it was on and off bleeding at the last few weeks before it officially stopped. I flagged out to my gynae and she told me it’s normal. Generally, it lasts 4-6 weeks for most mommies. Did PAP smear test and result came back all good. If you’re worry, just go see a doctor to have a peace of mind!
