Tubal ligation...

I got my tubes tied almost 3 months ago. After baby #3 was born. After she was born I had my first period on June 10..it lasted for about 5 days.. then I started to bleed again on June 22 it stopped on June 25. Then again on June 27&28 . Then I started spotting on July 10.. went to regular period flow in the 11th .. yesterday the 12th it was just spotting & so far today too .. ..my question is . IS IT NORMAL?? I mean after getting tubes tied ..oh & I'm breastfeeding .. so is it normal to have irregular bleeding ? TIA😊
