2nd period since birth to stillborn

Susan
I gave birth to a still born on June 18th. My first period was July 23rd and I was five days late but got my period on the 27th. What is weird is that before giving birth my period was always heavy and lasted a week. This "period" I spotted two days and only bled last night into this morning but now I'm not bleeding at all. Is this normal? Could I be pregnant again?
