Period post delivery?

Amy

My little one is almost 6 months old and has been sleeping through from about 6 weeks old. She's EBF and I haven't had a period since she arrived. Last week I'm sure I felt ovulation pains then a few days later I was extremely bloated, 2 days ago I had pink spotting and now nothing. Is this something others have had? I expected AF to hit with avengance when it arrived.
