Period ? Please reply

I posted yesterday but had no replies. I was looking for a bit of advice. I came off BC pill at the start of June where I had a very heavy red period, now my last 2 periods have started on the day the should have but they have been very light and very brown, hardly any red blood at all. Is this normal or should I go to the doctors? Has anyone else experienced this before? All my periods were Normal when I was on the pill Aswell :/
