Spotting

Hello ladies, I had baby 4 9wks ago and have already had my period but I was wondering if this has happened to anyone else but since my pp bleed finished I have spotted in and off for a couple wks now. Since if stopped I think I had 1 wk where I didn't. Got my period a week later after 6wk check up and since there I've been spotting ever since with a day in between where I dont. Is this normal and has it happened to anyone else.

No pill this time as hubby got the snip. So I dont need it but this is the first time without it. Has this happened to anyone else.
