First period after chemical pregnancy.

Ma
I had a chemical on March 29. I had very heavy bleeding for 7 days. This is my first period since the chemical and it is VERY light. Is this normal or should I be concerned? My periods are usually heavy. Starting off light and getting heavier by day 2. This time it's been about 3 days and it's still a light flow. Took a pregnancy test 2 days ago and it was negative.
