ovulation delayed after stillbirth?

jennifer

I delivered my baby stillborn at 20 weeks on July 28th. I had my first period on September 13th. It was heavy but normal length. I started spotting a week ago and just stopped yesterday. I use to have 21 day cycles so I should start a period today but I didn't. Has another else noticed a delay in ovulation after their miscarriage or stillbirth? I've been so frustrated and down the past few days.
