Anyone else taking mini pill bleeding?


I'm 16 weeks postpartum now. Got first period at 10 weeks and started cerazzete then. I then stopped sleeping for about 2 weeks and I've now been bleeding for about 3 weeks straight. Some days it's just spotting but most days it's enough I'm having to wear tampons and Sanitary towels. The doctor did say spotting is common to start with and normally settled after a few months. How is everyone else getting on with it? This has been 6 weeks and I just think this can't be normal. It's a great contraception cause I've not stopped bleeding lol.
